It's more about me....edit 1.0 todd

Hi Tom,

There's a lot of this that I quite like. I'll provide some comments and suggestions below.

When we stopped talking about our kids we grew up a whole lot.--effective first line and good grounding thought. It sets an expectation on the speaker's life experience and provides context. It also provides the interesting thought that once these people could focus on themselves they actually matured, which is something they couldn't do when they were obsessively broadcasting what their kids were doing.
Thing is, we started reminiscing instead…it was easier when you  weren’t sure.--There's some flab in this line. It's conversational but has some filler in it. I think all that's necessary here is "we started reminiscing instead" You want to provide the contrast to the first line but the Thing is is filler. The last phrase feels a bit disjointed in its meaning (I guess I'd respond to it by asking when are we ever sure of anything either as parents or individuals?).
You forget your own  things, mostly because you never see yourself in your past;--second use of things. I think you could cut "your own things" and the line would be much improved. With that cut this is a very interesting idea.
that’s when you value old friends. They remember more about you than you do.--Nice thematic setup for your conclusion.
‘Course, it’s a two-way thing… like when Johnny fell off the bowling alley roof…
I can see him as clear as day. He had a bad cut right in his gut.--I understand the desire to be conversational but I'd still avoid the "clear as day" cliche even when its deliberate and ironic--meaning that while you can sell it, it still draws too much attention to itself.
Circular. Landed on a piece of pipe. Fell twenty feet. Could have killed him
Yeah. We all remembered that... but whoa, was it Johnny or  was it Bob?--I like the question causing the doubt to exist in the middle of what WE ALL REMEMBERED. It's a nice touch the impermanence of memory.
Bob died last year…but yep, I think it was Bob…who’s arguing?--I would be inclined to cut the who's arguing. I would also possibly consider playing with the syntax a little to end the line on think (but yep it was Bob I think). Just because the end word plays to the theme. I think if you are going to add that Bob died last year in the next line you may want to haltingly remmeber. Perhaps above: Bob died, not then. Then below answer the question so that it isn't just a simple repetition.
 
Yeah…Bob died last year. He had it coming, we all said that. It was his face.--maybe "in his face"
His face changed and we all knew. Kind of sad-eyed, laughed  too late at jokes…--I think you caould cut "His face changed and"
only a second or so, but it was a sign. You know, like a plant in a pot
when it’s losing  strength and you don’t know why. You can feed it, give it water,--This is a brilliant extended metaphor
you can talk to it…hell, we talked to Bob and made sure he drank enough…
but the edges just turned brown anyways. He died last year. They said it was…--Love the edges turned brown anyways. I don't think you need the "He died last year" repetition again.
they said it was…just old age. How does that kill a man? I mean, we’re old , too.--You don't need this additional they said it was. You're trying to mimic the best of speech not all the pops and halting steps. I'd be tempted to break the above line on the question. I know we have different aesthetics on that--so, jus ta thought.
I asked Dan if he knew any more than we did. Dan said he'd been a good neighbour
but he'd gotten angry a lot of the time, Bob that is. Yep…he was angry a lot.--Introducing Dan seems unnecessary condense to the narrator making the observation about neighborliness and anger.
 
We’re talking about anger and age and memory…it’s what we do these days.--Don't like the second phrase here (filler). You may not even need the line.
Sometimes I feel that I’m getting a little brown around the edges…I get angry.--I think you're drawing the parallel too closely here. You may want to mention edges but not brown I mean the point is how could the narrator tell anyway--I'd be tempted to start this section with I get angry and riff from there (I get angry. Inside, I mean...)
Inside, I mean…you get angry inside and that’s what makes your leaves droop.
We all tell each other we’re fine, yep…I’m good…how about you? Been anywhere?--Don't like anything after fine on this line.
I can see it, though; and if I can see it in them they sure as hell can see it in me.--key line, thematic. Good observation.
It’s not the same as a tree, you know, in Autumn, when you expect it.--I would consider moving this line to follow the one that ends with roots below.
When Harry sits down at my table and sighs, I look at him and he is no tree…
the death signs are there…like a plant that’s been poisoned at the roots.--Not a fan of "the death signs are there" possible cut
I don’t know if I will be next. I can ask a friend for an opinion. They know more than I do
...about me.    --Like the ending. You carry off the theme well.

Just some opinions. I hope some of them are helpful to you.

Best,
