Hugging is pretty cool but it's pretty awkward when you're greeting people with hugs and then there's someone you don't know or only half know and you're not sure whether it would be appropriate to hug and so you just stare for a short while and then one of you decides to hug and the other decides a handshake will do at the same time, and then you notice so you both try to switch unnoticeably but it doesn't work since you both do it and you both stop dead and then it's all "ahh hmmm"
