Here are a few things Thai that puzzle me. Not in any order of importance. I'm sure you can add to the list;

A motor bike taxi helmet has never given me headlice.
Thai street food hasn't killed me nor even made me ill.
No matter how many phones a thai boy has stolen from him he always has your number.
Thai dogs never get run over while sleeping on the road.
Thai motor bikes always expand to suit the size of the family.
That thai school uniforms can be so white.
No matter what you say or do a thai landlord will never refund a deposit.
Isarn girls in the beer bars are so loud and screechy while the Isarn beer-bar boys are so quiet.
