I wanted to see what people's thoughts are. If you are in a house, and a neighbor keeps parking their car at the sidewalk parking directly in front of your house/yard and leaving their driveway and sidewalk parking completely empty, would that be considered rude? Isn't it common courtesy/knowledge/respect, that you should only park in your own driveway, or the sidewalk parking in front of your house, and not park in front of someone's house every single day? Yes, I know that the sidewalk parking in front of a house does not belong to anyone.
