It starts like this:
Hello hansum.
Were you flom?
How long you stay Thailand?
You single?
You speak thai?
When they know you a bit better, they dig deeper:
Where do you work?
Where do you live?
You buy or rent?
How much your salary?
You have a car?
Which one and how much?
Later:
You want new family?
You want more children?
The longer you are here, the more thai you speak, the more girlfriends you had, the less interesting you are for them.
They know that you know most tricks out of the book and have to fine tune their lies and stories.
Better to get a completely white farang who just steps out of the plane, never has been in thailand, never had a thai gf, doesn't speak a word thai and is quickly impressed how lovely she is and how great her relationship to her family, especially brothers, is.
She will make sure that you quickly will know the lot.
Too many come over and want to impress. Suddenly everyone is a Dr or fighter jet pilot.
Each on at least 15k $ a month and owning villas and sports cars.
They go shopping with the girls, little do they know that the guy is maxing out his CC.
Some even rent a high end car to drive up to the village to impress.
She now has you on the hook and how to you explain that you are just "plumber Joe from Norwich, on a 24k£ a year. ????
Now pay back over 1 year what you spent on 2 weeks holiday, trying to impress the lady.
