Interesting to see, I find, just how wide the gulf (still) is between the classes.
It never fails to amaze me how both sides can still have such alien customs and ideas.
For me, my 21st was a pretty standard night out with friends, as i'm sure it was for most people on here, there were no speeches, in fact aside from a few drinks, very little special attention was paid to me. I wouldn't have wanted it any other way. The thought of a large group of people gathering to celebrate me getting older, at that age, would have been mortifying. Yet as the OP (and a few others in the thread) have proven, for some this is almost an expected kind of event and entirely normal.
No real point to this response I guess, I just find it interesting. Different worlds and all that.
