My cousin had the following conversation with our grandfather this morning:
Grandpa: When you go to the big city don't let boys put little white pills in your drinks at the bar.
Cousin: *laughing* Right, I won't let that happen Grandpa.
Grandpa: You laugh, but I'm serious. They do that you know. I think it's probably marijuana.
Cousin: You know, I think you're probably right.
Grandpa: Or heroin.
My grandfather is full of useful advice!
