Love is like a flower

[joesammsington]

I don't know what you're going on about with the second quatrain. It was free of grammatical errors and the syntax looked fine to me. Also, one does, in fact, reminisce of things. You could say "about", but it doesn't quite roll off the tongue. All of your other edits were great and looked fine, and they are appreciated, but if you could be a little more specific on the second quatrain it would be helpful.
And furthermore, I clearly said autumn followed summer. Seasons end (hence the "all things must end") and new ones begin. What exactly don't you comprehend?
