Well, I used to hate when my parents would answer one of my queries with a "because I said so."
Me: Dad, why can't I stay up and watch Dynasty?
Dad: Because I said so.
Me: Mom, why can't I play handball after dinner?
Mom: Because I said so.
But, here I go:
Don't put a comma before the word because.
Because I said so.
But, what about...
Don't talk back to me!
