we are in a foreign country, so people do not have the same social pressures as at home. so people are more free to be themselves. i make hundreds of friends when i'm traveling, and some i keep in contact with, others i don't. life is busy and those who are willing to keep in contact will do so.
one of my best travel mate from new zealand is going to travel with me again in thailand, and the last time we partied was 3 years ago in laos!!!!
