Today is Sunday and my next door neighbor started mowing his lawn at 8:00 AM. I think that was kind of rude because a lot of people like to sleep in on Sundays. I don't think anyone with close by neighbors should mow their lawn until 9:00 AM. What do you think? How early is too early to mow the lawn?
