Keeping up for some reason.

Our next door neighbors are quiet and elderly. They are however finicky about their lawn. My husband was yelled at by then not too long ago for mowing a part of their lawn when he mowed ours. The reason he did this was to decrease what they had to mow. We were gifted a broken riding lawn mower that my husband repaired. Oddly enough this week our elderly neighbors bought a brand new riding lawn mower for their healthy live in and unemployed son to use to mow the lawn. I don't understand spending that kind of money but oh well. The truth is that my husband would have mowed their lawn entirely had they not yelled at him. He started mowing it before their son moved in and never stopped. I guess maybe they want the son to do a little more work or is it less when it is done with a riding lawn mower? We certainly aren't the Jone's and they don't need to keep up with us but whatever makes them happy I suppose.
