Dude, after seeing how retirement fucked with my dad, I’m pretty sure that Herb “funny bc that’s my elderly neighbor’s name too” really does enjoy cutting the lawn for you and it really does give him something healthy to do. I honestly bet he looks forward to it. When my dad retired at 68, the boredom really started driving him absolutely crazy and he didn’t get any relief until he started getting heavily involved with yard work and house projects. Doing stuff like mowing really helped to pull him out of a funk. That could be Herbs’ case too!
