Annoyance for the day

When my father-in-law always says we leave lights on in the house everywhere (which we don't). First of all, you don't pay the damn bill. Second of all, I have 2 two year old boys as tall as fifth graders who like to turn lights on (and off). So, if you want to go around following them and turning them off be my guest. Don't fucking bitch about how many lights I have on in my damn house.
