Hello. It may be a question about western culture... Our school has a foreign teacher from the UK. He is a nice huge teacher with a little gray hair. He doesn't speak Chinese, so I helped him obtain taxis a few times on my side. I enjoyed listening to him speak English. He asked me if I would like to be his assistant today. If I can bring him some help, I am more than willing to say yes, because there are very few students who can speak English in our school, and his life may encounter some inconveniences. He mentioned that the assistant needs to go to the bank with him once a month, and if I accompany him as an assistant, should I be by his side or sit separately from him when taking a taxi or bus? I feel a little uneasy thinking about it. I hadn't actually met British friends in real life before, and I didn't know much about cultural etiquette. So I would like to hear the opinions of kind-hearted people on how to deal with it more appropriately. Thank you!
