I said nothing of the sort. I said I was constantly reminding him to watch the seat in front of him. You see some parenting is reactive and some proactive. Me reminding him constantly to be careful of the seat in front was meant to be prevent him from hitting the seat. When he got up or moved around I said to him "make sure you don't hit/grab/kick the seat" so he would be aware of it before he did it. See how that works there?
On the very few times he did contact the seat I admonished him to be more careful. Therefore I felt the guy's complaining was unjustified and felt I couldn't win.
