When Clothes No Longer Fit

Laurence must have dug deep in the closet today, because he came downstairs with a shirt he hasn't had on in a LONG time. The shirt was hitting him right at the waist, bordering on too small, but it's a favorite so I couldn't bear to ask him to change. I tried to break it to him gently with, "I love that shirt, but it looks like we'll have to retire it soon." (This is what we call putting clothes away to hand down to Loic.) He said, "Oh, I hope not TOO soon -- I really like this one!" I said, "But soon we'll be able to see your belly button, and that would look pretty silly!" And his response: "Well, yeah, but that's how Dora's shirt is...you can see her belly button. And she doesn't even seem to care."
