I was on a flight in F next to an older gentleman, and his young, attractive wife and child in front. The kid thought that he could speak at any pitch and volume that he wanted (I understand kids crying, but this kid was at the age where he could have been politer about his volume- across from me were two kids around the same age who read the whole flight). He was constantly pestering his parents, the FA's and people around him. At the end of the flight, he ran into the cockpit when the door opened. The FA at this point had it, but rather than confront them he just efficiently showed them the door. Keep it classy UA .
