Obviously you are not a teacher. You may have anger management issues too. If you are unhappy with your daughter`s behaviour, there are surely other ways to deal with it.

Older farang male marries Thai woman without understanding much about her culture. Expects her to adapt to his ways but is less willing to reciprocate, sadly a common occurance. Either get a home with a kitchen partly outside, become acculturated or join the line of couples who are unsuited to each other.

A fair price is whatever you are willing to pay. Staying longer and gaining more knowledge of local prices helps in making more informed decisions if you have the chance. This is harder to do in places with many farang so avoid those farang ghettos and make more Thai friends. This takes time but it is more rewarding, not just in a shopping sense. If you are on a short holiday, enjoy, don't worry for minor purchases but don't buy anything major without giving it more thought.
