In my understanding, I always thought that a friend is not measured by money. So, when you mentioned the money, I feel very frustrated. Want you to accompany me to walk around, because I want to get to know you as a friend, not as your guide. I can pay for both of us, but I do not want to simply because the transaction and pay you. Maybe in different countries, people's thoughts will be different, but I think, believe you will understand.
