Very Good!
I have told my 3 kids that they are absolutely not allowed to kick the seat in front of them and if they do I will tie their feet to the arm rests. The last time we flew back from Salt Lake City my 5 year old son sang the theme song from Sponge Bob Square Pants for 2 hours without stopping. The people sitting in front of him wanted to kill him and I was really embarrassed until the flight attendants told my how rude and hateful the people were to them. The flight attendants said they enjoyed Sponge Bob, all 2 hours of it. But at least he didn't kick the seat.
My mother tells me what brats my kids are and how I was such a perfect child I would never do what they do. I told her compared to their peers they aren't too bad. She saw some of their peers at my son's birthday party and said they were little savages with oblivious parents.
