We are not playing jeapordy; the question comes first.

By the way, requests must come with a question mark. For example, if you need a pen, the correct way to phrase that is: "Do you have a pen I could borrow, please?

On the other hand, the statement "I don't have a pen" is just fact. It's not a request. Until you know how to ask politely, you are unlikely to get a pen, or anything else.

Be civilized: say hello to your neighbors.

Is there some valid reason why you don't acknowledge your neighbors when you see them walking (and waving at you) in your neighborhood? It's the only civilized thing to do.
