He has no regard for his neighbors, most of whom would be fast asleep at that hour.
why does this guy on my block choose to mow his lawn at midnight all the time?
He's a vampire...or just a colossal jerk
Maybe he's an albino and fears the sun or he's allergic to sunlight.
Closet sociopath.
Perhaps cos you coughed at him and he didn't like it ;) get rid of that turtle in your throat.
If you live within the boundaries of a community that has bylaw provisions for unnecessary noise during that hour .. Then perhaps he is daring you and your neighbors to report him because he feels the need to pay a hefty fine for being such an idiot . I'm think'n you should abide and call the police and help the guy out.
He wants to make sure the headlights on his mower work.
I like Gator Blu's answer. After all, it would be hard to mow holding a flashlight.Â
As for why, some people are just idiots. Had a neighbor who would, like clockwork, fire up his mower every Sunday morning all summer at 0630.Â
