Be loud and be proud
One reason that Thais should study English is to make their family proud. Your parents and grandparents will be proud of you if you can speak English. Your younger brothers and sisters will look up to you. Everyone you meet for the rest of your life will have more respect for you if you can speak English. Your teachers, your friends, the monks, people at the market, people at the bank, taxi drivers, farmers, everyone in your village will respect you. And you will be proud of yourself for learning a difficult language. If you can speak English everyone will think you are an educated person.
