You can toss me in with the old fashioned bunch here. If that was my 3 yr old acting that way he would learn real quick that the behavior is unnacceptable. I've had all I can handle of today's ill behaved kids, and the excuses that come along with the behavior which shows me the parents know the kids are brats but choose the easy way out....let the little darlings do as they please.
No way would any of us ever have gotten away with rude behavior such as this and no way would my own kids have gotten away with it either.
