One of my friends come to me and said “Dingchao, I need your help!”. I was shocked by his look, I thought there must be devastating thing happened on him. But he told me his problem is he was abandoned by his girlfriend. What a shame! I didn't regard it as a problem that is hard to solve.
I told him “you don't need my help, my friend!”, I didn't explain anything further. Then I focused on what I was doing and ignored him at all. He got out of my house five minutes later. I think I must know how to deal with it now, because I see him very happy today.
