Songkran is a festival in Thailand where thai new year is celebrated with a huge water fight. In Chiang Mai, if you go out of your house during Songkran, you wont go back dry, because everyone turns mad this time and will throw water at you and innocently grin back and will say “sawadee phi mai” or happy new year.
Well, its supposed to be okay if clean water will be thrown back.. but be careful of water in the form of ice! and water in the river, or water in the sidestreets!
Reminds me when I was in Kolkata celebrating a similar activity – holi. *flashback*
