Wonderful, wonderful, wonderful. The poem only got better as it went on- the beginning made me smile a little, and think- I could tell that the narrator really cared for whoever she was talking to. The middle really absorbed me in as well- it wasn't awkward or average as middle stanzas can sometimes be, at all. And the last two stanzas were by far my favorite, especially the second-to-last one. It made me feel a little sad- which I assume is the poem's purpose.
Excellent.
