Me: Owwwww…
Butterfly: What’s wrong, Daddy?
Me: My leg hurts. I just can’t seem to sit in a position in which some joint in my leg doesn’t hurt.
Butterfly: Sorry Daddy.
Me: That’s okay. It’s what happens when you become old and decrepit and stupid.
Butterfly: That’s not true, Daddy.
Me: It’s not?
Butterfly: No. You’re not stupid.
