She's already taken

Today while I was watching Perrin and Pason, at lunch Perrin (age 6) asked, "Is Laura my sister or my friend?" I said, "She is your cousin AND your friend!" Then he said, "When I grow up I'm going to marry Laura, because I love her!" His dad, who was home for lunch, told him he couldn't because they were related. I said, "And besides, Laura already has a boyfriend she's going to marry." Perrin didn't know who I was talking about, so I explained it was Grayson who came with his sisters to Laura's party. Here's a picture of the handsome devil!
