It's kinda weird, 10 or so years ago I loved being in the crowds. Nowadays I avoid crowds and enjoy being by myself. I am not antisocial, I get along with most people but I prefer being by myself. Maybe it's just being confident or maybe I've had enough of people who have little depth of character.
I hope that you had a great time up here and that the weather wasn't too bad. I take it that you're looking forward to going back home to Thailand?
Take care and hopefully see you over there at some point :D
