A floating spar to men that sink and rise and sink and rise and sink again

I saw this on a friend's blog, and I immediately had to do it--

The trick is this: I will tell you my favorite poem [which is, in fact, a lie--I will tell you my favorite six poems]. If so inspired, you may add your favorite poems in the comments, and I'll add them here.

Mine:

For John, Who Begs Me To Not Enquire Further by Anne Sexton

it may not always be so by e.e. cummings

Homage to My Hips by Lucille Clifton

It Was Raining in Deflt by Peter Gizzi

Sex Without Love by Sharon Olds

Love Is Not All by Edna St. Vincent Millay
