Lily and I were watching some episodes of the Legion of Super-Heroes, when she said that next time we go to a comic convention, she wanted to wear her flight ring. I suggested that it might be fun to go as Saturn Girl. She agreed, and then I said I should go as Bouncing Boy.
She said "You can't go as Bouncing Boy, because you're" and I thought she was going to say "too skinny",
but she completed the sentence with "too old" instead.
