And (in all fairness) my son is a very polite and caring person. It's just that he picked up a few odd expressions in an American high school
I have no doubt, but going over to the U.K. the first couple times and spending extended time there a lot of their expressions sound odd to my ears. I still kinda wince when I hear "What ya on about?" I know it's not rude, but it sounds very rude to me if I look at the words alone, but the INTENT and way its said is obviously not rude.
Or I was going into a pub and the guy said "Hats off fella." I took that as rather rude, as "Hey take your hat off, with "fella" being a diminutive." If someone said that to me in the states, I would feel talked down to. My fiancée explained that no, it's just a common term like some would say "dude" here.
Anyway babble over until the next couple posts...
