I'm low income and I live in an area of middle class people. I get a lot of dirty looks for my dandelions and my clothes line. I don't use weed killer, I don't water the lawn, and I mow only when I have too. My poor neighbor looks like his eyeballs want to pop out all the time. I've even caught him sneak spraying my weeds! He likes to tip toe over and do the 18/24 inches on my side of the fence line. I haven't called him on it because it's not near my food, but let go dude. Relax!
For the love of all that is holy I want to spray my neighbors' lawns! I mow and edge my lawn weekly, so it's so infuriating when patches of weeds migrate into my lawn. Maybe you should do some weed pulling for his benefit?
For what it's worth, the birds and the wind will spread those weeds at least as fast as the plants will migrate themselves.
One of the big irritants of my end of the street is my neighbors who mow their lawns every week. Not because the grass is high, or not because they need more salad ingredients, or not because the homeowner's association is after them but because... it's that day of the week and it's time for an hour or two of noise! They start with a gas-powered mower, switch to a two-cycle gas weedwhacker, and finish up with (you saw this coming) a gas-driven leaf blower. All at max throttle/RPMs. Because, of course, none of those dead grass clippings could be allowed to litter a perfectly-manicured lawn.
These are the same people who wash their car every week because... it's Sunday morning. Not because it's dirty or because it's corroding or because their kids want to earn some extra cash but because... "Oh, look at the calendar, it's time to wash the car! Hey, maybe the leaf blower will dry it faster!"
We mow our lawn about three times per year... and our growing season is 12 months long. We use an electric mower and an electric weedwhacker. I fire up the gas-powered weedwhacker about twice a year when the back slope's California grass gets about head-high.
I my daughter last washed our car in 2013. So far so good. She'll probably visit us again in 2019.
When I work on it in the driveway, I get some funny looks from people walking by.
Maybe they're just intrigued by your GU boxer shorts...
