While I'm thinking about it, here is a pet-peeve (aside from the phrase "pet-peeve" being one of my pet peeves (I don't know what I was hyphenating that for)):
When people begin the answer to a question with "So..."
Is "So..." the new "Well..."?
Here's an example.
Q "Is there a cost of admission for students?"
A "So, students have to pay $6, but it covers supper, too."
What? Where did that come from? Don't start the answer to a question with "SO." I know, you've heard other people do it, and you've started doing it out of pressure. Don't. Stop it before it's too late. I blame young people in California for this.
It is different to use "So" in the form of a non-sequitur, for instance walking into a room and saying, "So I just peed on myself!" That's funny. That adds value.
But if someone asks you where you peed, don't answer by saying, "So I just peed on myself!" Leave off the "so," because it is useless. ...Although that's actually quite a bit better than the example I gave above...
