Expiration Dates

My eleven-year-old daughter has had a really nasty cold.  Last night, I told her to rub a little Vicks VapoRub on her chest to help her breathe.  She picked up the container and examined it.

"Mom, this expired in 2002.  It's ten years old."

I took the container and looked at it.  "No, it's not ten years old.  It's eleven years old!"

"Mom, this thing is older than me!"

"Wrong, again girlfriend.  You are six months older.  I think you need to work on your math skills."

She looked at me funny.  "And you need to work on your expiration date reading skills!"
