I don't know how many people actually mow lawns on Mondays.
People on vacation? Retirees? People who were away all weekend?
But you can't blame someone for wanting to get at it early today.
Ordinarily you might have a beef about the sound of a mower interrupting the morning quiet. If it's super early, I mean.
But today, maybe it's understandable.
Of course, another option is to let the grass go a few days and see if life as we know it is able to continue.
