Even though we get along perfectly and never argue about anything, from childhood my youngest brother has always done the opposite of anything I ever asked of him, so I finally quit asking. Even now, if I were to ask him to move a piece of junk out of the way, he would stack five more pieces on top of it just to let me know I can't tell him what to do. Which is fine, but I just find it to be odd, and even more so today because our youngest sister has been here for the past week and he has been following her around with a chainsaw, a lawnmower, and a junk trailer, doing whatever she points out as needing to be done.
However that works, she almost finished the pond this afternoon.
