A. "Knowledge is power."
A. Letting bad people into my life, and letting them stay there much too long.
A. A good book, a pool, a cold drink on a sunny day, with my loved ones cheerfully occupied nearby.
A. "Oh *!" and "Damn it, where is it?!!" and "Get out of there!" (That's to the dog). Also, "Love you," and "Hey sweetie" and "Give it a go, you never know" and "Drive carefully" (see question #5). "You won't believe what happened" is being used a lot lately. So is "Oh, I'm a lucky woman." If the backspace key were a word, that would be in there, too.
A. People talking loudly in the library. I also hate it when someone picks up a book I'm in the middle of and starts reading and perusing. It's like cutting in between a happily dancing couple. I'm very clutchy about my books.
