Circle Of Friends?
I'm not quite sure it's a 'Circle' of friends.
That's an enclosed structure yet it has no end.
A rather would liken it to a tree.
Every leaf I turn over could be a new friend for me.
And when I find the new friend of a leaf.
It's attached to a few others within reach.
Like the branches on the tree,
a few more reach out to meet me.
Then on and on it goes,
as my little tree grows
