[Ivy Addresses an Oak]

[HalfOpenArms]

the first line is solid, it means something, it has an image of something.
the second has an image but isn't as solid (in such a short poem all the wortds should count as much as possible) that hauled me skyward] or something more succinct.
the last two lines say a lot to say a little.
great effort

You were the scaffolding
by which I hauled myself skyward.
If not for you,
I would have never seen the sun.

"the last two lines say a lot to say a little." Oh boy, I can't tell if you meant for this to be positive of negative. I'll play it safe safe and assume the latter, and edit accordingly.

How's this:

You were the scaffolding
that hoisted me skyward,
showed me the sun.

Thanks for the kind words, everyone!
