I feel too bad till to now. last week , I post an advertisement that I am an experienced Chinese tutor, can teach Chinese in two ways, face to face or online teaching. So I meet a young guy who come from Europe, we talked to each other and confirm begin to teach from Tuesday at 8 o'clock in the morning. So I first prepared the book and several exercise books for the young guy. I didnt show his real name, just call him Chis. On Tuesday morning, I got up early, and carry the big bag with full of exercise book to the pointed place. I received a call from Chis, he told me he suddenly have a meeting, felt too sorry to me. I think it is an accident for him, so I come back. and in the afternoon of that day, he send me a message, expressed too sorry, and he will make up his absence on Wednesday morning, he was sure he will be there 100%. On Wednesday, I went to the pointed place which is a coffee shop and reading room for waiting "my student", after 1.5 hours, he still not come. I try to send message by WeChat, but no reply. The guy, Chis dispeared, nothing explanation, nothing sorry. He played a wicked trick with me. But, what is his purpose? What's the meaning for doing this? Is it happy to waste other's energy and time? I really feel angry.
