It seems that Christmas is an increasingly popular holiday in Thailand, despite the fact that Thailand has managed to (for the most part) resist the infection of mass Christianity.
All around Bangkok, giant neon snowflakes, chubby snowmen, and full-size reindeer sleighs are everywhere. “We Wish You a Merry Christmas” and “Jingle Bells” pipe nonstop from loudspeakers. Weeks before the holiday, a Christmasy atmosphere is in full swing in this predominantly Buddhist country.
