Prim

Prim is a student, age 20. She told me she was from Issan, in Northeast Thailand. I said she didn't have the usual Issan characteristics, such as a light skin and a flat nose (the Issan people are very self-conscious about their squidgy little flat noses and having them enlarged is a staple of the Thai cosmetic surgery industry). Prim just smiled and said "no". I suspect she is of Khmer origin: the Khmers are darker skinned than most Thais, and of a different facial type.
