It's like a story, a good story at that. :)
This was just lovely and I like the part about the half smile. This poem is personalized but still easy to relate to, having a summer love... Great job!

Hello! This is absolutely gorgeous. You did an amazing job telling your story in poetic form, and I love the repition that you use with the line "she remembers him." It really shows me, as a reader, that this boy has affected her life, no matter how short of a time he was in it. I love this! :)
