One of my favorite stories about Peter's childhood is the one about his youngest sibling, Jacob, where he would wear a blue Wal-Mart bag (and only a blue Wal-Mart bag), by making leg holes in the bottom and pulling the handles over his shoulders. He would then proceed to jump on the trampoline exclaiming, "I'm Mario, I'm Mario!" We decided it would be fun to try one on for size with Piper.
P.S.--Jacob is on his mission right now, so that's how I'm getting away with posting this. Come to think of it, he probably would be proud to claim this story for himself. Oh, well.
