Retiree Rant

I have not been able to figure this one out. Our neighborhood is populated with retirees. Some do volunteer type work and what not during the week. However, I assume they have more time in general than this hard working couple. On weekends, these retirees get to it with their leaf blowers, lawn mowers, and other very loud lawn equipment. This sunday morning, 9 am, someone was out with their lawnmower. Lordy- cannot we enjoy some peace on our weekends! What is wrong with a rake?
