Here's a funny story from many years ago.
One evening I broke curfew and got home about an hour late. My mom was sitting in the living room when I arrived.
"Where were you?" she asked.
I told her that I was out at a girlfriend's house.
Wanting to tease me a little, I guess, she replied, "Oh, really... What were you guys doing this late?"
I told her that we had just been hanging out, nothing special.
"Nothing special, huh?" my mom said. "Your shirt's on backwards..."
Immediately, I looked down. "No it's not."
Slyly, she looked at me and said, "Why'd you look, then?"
Nice one, ma.
