  A thought: So you're at the grocery store and you're in line waiting to pay for your stuff (this is especially applicable if it was a long line) and you get there and the lady (or guy) behind the counter says, "Will that be everything for you today? " HELLO? why would I have just stood in line for like, 10 minutes if that wasn't everything?? "No actually, i just came to drop off my stuff... i still need to get some eggs, potatoes, celery and peanut butter.
You wouldn't mind just waiting for me while i pick up those thing would you? " I mean, really people. think before you talk! with quesitons like that, there's clearly only one answer. Example #2: "Can I ask you a question? " well what am i gonna say? "No, actually, I would prefer if you didn't. " Obviously people don't ask that expecting a no. Or, "Can I borrow a piece of looseleaf? " Borrow? Why would you want to borrow looseleaf? Are you just gonna stare at it or something?
Cause I sure don't want it back if you're planning on writing on it. Just something to think about. Have a pleasant day :)
