A joke about a bottle of water

A colleague asked you for a bottle of water, and then you gave him the money. He said you can't play with this child, which means it's just a bottle of water. You are too serious. In fact, it is normal for colleagues to help each other and get along well. He buys you a bottle of water, but you don't have to give him money. It seems a little far away. You can buy him a drink or a cold drink in the future. That's what happens between people. You respect me one foot, I respect you one foot. Friends are friends.
