Just to add a tidbit... since China has a one child only policy, it is common for parents to spoil rotten their one (especially if it is a boy). I’ve read articles that say the young boys in China are more rude, fat, and allowed to do things and this is now an issue there. Just a thought.
My family and I traveled back home on Monday from Minnesota on an American Airlines flight that was maybe 30% capacity. There was a Chinese family (dad, mom, 4yr. old boy, 1 yr old girl) three rows ahead of us. The children were RUNNING around in the aisles, and I had to verbally tell the 4 year old not to pull on the emergency door handle, since his parents were not about to do it. The flight attendant at one point had to tell the mom that the 1 year old girl was not allowed to be in the emergency exit row BY HERSELF. Geeesssshhhh. Where was the Tiger Mom?
