Sorry - I forgot to answer your other question, Andrew - I had strong suspicions that there would be an initiation for the hockey club, because ds2 plays hockey too, albeit at a different university, and his initiation involved drinking, dirty pints, more drinking, a very muddy obstacle course, and ended with him getting his head shaved. There may have been noxious substances in the mud of the obstacle course. Oh, and they had to brush their teeth and then drink grapefruit juice.
So I was not surprised that ds3 went through an initiation - drinking, and dirty pints seem to have been the major theme of the evening. And if a more senior club member meets him anywhere, and he has a drink in his hand, they can tell him to down it in one - for the whole academic year, I think.
He does still have all his hair, though. He is fine with drinking things that make him sick, but go near the 'do at your peril!
