Growth:15

It used to be that what you thought was what I thought I should think.

If my thoughts to yours unmatched
--foundations, crumbling, my tenuous feet--
went flailing I down the pathway of lost.

But now I understand [with my big girl eye]
that you can think what you think, and I can think of mine,
and still together life we can stand. Walk, even. Dance.

It's intimacy, isn't it?
Not destroying of me;
Foundational.

[grow, verb: to increase in size or substance; 

to spring up; to develop to maturity]
