Hello Thai people who don't understand other cultures. I invite you to learn the reasons as to why I'm wearing a rude shirt (it says "dick" in Thai).
I'm not in Thailand, probably not going to go to Thailand, I'm not Thai, I'm not a teacher, there's no Thai language in my country. There is a culture of joking like this in this country. So, what problem can you have? I don't understand. It's better for you to go back to Thailand. Australian culture accepts being a larrikin (คำภาษาออสเตรเลีย ) Australian culture is very different from Thai culture. Here is an example. Australians don't really respect the monarchy in a serious way. But we still love them, we love our country. This culture is because we dislike pretentiousness . We really don't like using very formal language. We don't like royal culture or high class culture because because it's unfriendly. It's too serious. It's not fun. It has no room for jokers. We like blokes (ภาษาออสเตรเลีย) who joke around as a larrikin. We like being a bit rude. We like speaking honestly and openly, and honest and open people don't make their friends angry in Australia. We don't like polite people because we don't like lies. We like being a good mate (ภาษาออสเตรเลีย) . We don't like people of rich and polite culture. Cultures of relaxation is better. Cultures of good mates (ภาษาออสเตรเลีย) who joke around is better. Having a beer and relaxing is better. We like being laid back.
