This is a beautiful poem, and thoroughly deserved front page winner. The way you seamlessly interpreted the prompts into this poem is really well done. I'm a big fan of poems that have the persona's individual thoughts/memories entwined. The nostalgia here was palpable.
I don't know why but whenever I think of your poetry, I always think of trees. I think it's because of how much I was moved by and love your other poem, "Old Tree" so to me, it's really suiting that your first poem back after a hiatus revolves a tree, and the experiences had in a tree-house :) I really like this piece, it used the prompts so naturally. Hope this is the start of more poems from you!
