different culture

I learned a lot of different culture in the USA that I had not known before. First of all, I need to pay tip when I have meal in a restaurant. In my country, a bill includes every thing, such as service fee and tax. You don’t need to pay addition. Also, American people will say “Hi” when they meet you on a street even they don’t know you. However, if you say “ Hi” with someone you had not known before in my country, people will think you have some problem. In addition, freedom and independent is very important for American people. They don’t want the other people control them too much even girl friends. They always separate ticket when they have meal together. It’s very strange in my country. In Taiwan, a man always pays every thing for their girl friend when they are dating. There are too much difference culture between America and Taiwan.
