This one time last week I found myself alone in a Gap dressing room with an armful of clothes, mysteriously all in my size. I had no choice but to try them on. You would have done the same, right? I mean sure it was sketchy that I didn't have any clue how I ended up at a Gap 20 miles away from me, but when cute clothes are in your arms you try them on. It's just polite. I walked away from the store with this pair of pants. (And yes, I did remember to pay.)
Amnesia shopping -- that's what I'm going with on this one.
