We got a letter from them about parking our car on the narrow street in front our house. We think the couple across the street sent it because sometimes they have a hard time backing out of their driveway when my brother parks in front of it.

Yeh, sounds like they're just being cute about telling you to move your ass.

You must be one of the most egocentric asses in this area.

Why do you keep parking your car directly in front of their driveway? That's considered being a bad neighbor, unless there is no other option. Common sense suggests that you should try to park a few car lengths to either side of a neighbor's driveway, unless there is no other space available.

Try to have at least some consideration of others, rather than asking stupid questions that any reasonable person can answer themselves.

You're probably the same assholes who park directly across from another car that is already blocking 1/3 of the small road, forcing the entire neighborhood to alternate between the cars coming in either direction. Either you do it on purpose just be assholes, or you are so clueless that it never even occurred to you to think about how your actions impact others.

Do you, by chance, hear car horns late at night whenever your car is parked in such a way as to impede traffic?

If so, I know what street you live on.
