Well it's now 2558 in Thailand. (2558 years since the buddha died) And thai people like to celebrate by having a huge water fight (to clense you and start over a new year and wash all the sins away)
People rub this white paste over your face and then it gets washed off and it happens over and over again. You are not allowed to refuse the water and you can't get mad if you get sprayed in the face (happens every 10 seconds)
It is the biggest thai festival throughout the year and EVERYONE attends to it. It is a 3 day festival and is amazing fun.
Happy thai new year and hoped you learnt something c:
