Kids These Days

If I let myself cool off for half an hour I probably wouldn't write this. But since I'm not cooled off...these kids were outside throwing rocks. One hit our window. I went out and asked them to go somewhere else because one had already hit our back door and I don't want to deal with a broken window tonight. One of the kids said "how did we hit your window?" The nerve! I recovered quickly and said, "I don't know, but it did." So they reluctantly left. Why is a 10 year old boy being so rude? I'm a little miffed.
