Far too often I hear or read in forums about expats burning their bridges. Maybe that's okay for an expat without family, who for some reason has become estranged from friends, and has nothing or no one to connect him/her with home.
Oddly enough, many of those expats really haven't lived in Thailand long enough to be sure they are here for the long run. When times get tough emotionally and spiritually, a connection to home can sure make a difference.
For most of us, it's something to think seriously about avoiding. Keeping your support network in place makes good sense.
Most family and friends naturally worry about your life in the wilds of this foreign and mysterious land. So staying in touch on a regular basis alleviates concern as well.
