I'm...barely ever out of flip-flops. Even in the winter. I get a lot of crap for it.
I deserve it, actually.
Kyle and I went to St. Louis in March for an Evanescence concert (which rocked, by the way. Amy Lee was SO much better than the last time I saw her) and I wore my flip-flops all day while we walked around St. Louis. We went to the zoo, the Arch, and just had a day of it. Me, being the idiot that I am, removed the calluses off my feet the night before, which were on my feet to begin with from the rubbing against the plastic on the flip-flops all the time. Needless to say, I came home with 10+ huge blisters on my feet.
But I still wear them all the time.
