My son is the best

Yesterday I bought my son some clothes. I put everything into a big bag. When I got back home, I could tell he had gone through the bag and one item was sitting on a chair. Alone.

Son: Mom, I don't like the Superman boxers.

Me: Oh, ok. Why?

Son: I just don't like Superman. Batman is cool. Not Superman.

Me: Who is seeing your underware anyway?

Son: Mom, I change in the locker room. I don't want people to think I like Superman.

Me: (joking) See, it's a good thing I didn't get you the Wonder Woman ones.

Son: No. Wonder Woman is cool.
