You’re having a rough day. Seems like everybody wants a piece of you and they aren’t kind about it. So you put on some ear protection, grab your leaf blower and step outside. Nobody bothers you out there. The leaf blower yells nonstop the way you wish you could and even though you aren’t doing the yelling, there is still something cathartic about the noise. It creates a bubble where you are left alone. As the minutes pass and the debris collects into neat little piles, you can slowly regain your calm. The urge to explode, unleashing your anger and frustration, in an irreparable way ebbs and you feel like you can hold your shit together for a little while longer.
Or they are in a feud with their neighbors and are trying to piss them off.
