Like it or not, you will have to get used it if you plan on integrating into British society (or american, canadian, ...).
I rarely ask people how they are. The only time i'll ask people is if i haven't seen them in a while (like 4 or 5 months or more), even though i don't really care at all. that's more just to try and get over the awkwardness of the situation, which usually doesn't work.
plus, i just flat out don't really like the English. I don't think all English peoplel are bad, i've met a few good ones. alot of the women i've met are fairly nice, but most are younger, plus i didn't have to be around them for all long time. i think there's alot of arrogance in the English, especially alot of the young men. that's just my take, i'm you'll say that about Americans, but we don't really care.
so remember, no offense to the good and kind english here.
