Duh. I am sure it is pretty scary to have someone repeatedly banging on your door late at night. However, you can call the cops and then get some sleep!
Duh to the girls too...I can't help but feel that there was a bit of mischief in their hearts....hence banging on people's doors late at night with six measly cookies. Brats. If I were their parents I would have read them the riot act. They could wind up dead if they scare the wrong house.
They had their parent's permission. The only complaint was from these two pieces of work.
Years ago, some friends and I rang the doorbell of a neighbor at night and ran off. The neighbor was upset, and later told me that her brother was killed doing the same thing when they were growing up, rang the bell at a house of a very cranky fellow and was shot. It never seemed like a smart thing to do after hearing that.
