The final stage of my master's thesis It is a delightful day today, because my mentor reviewed my draft thesis and approved my research methods and final results. Although he did not compliment my work, I think no criticism is the big praise! haha! He is an extremely strict, stubborn person and hardly praise us even when we do something good. What he normally say is "Well, make an effort to do it better". As a result, all the other fellow students of mine have been scolded seriously because their work was not catering for his requirements. Actually I felt a bit nervious when I sent the thesis to him, getting criticism is not comfortble after all. So everhting is going to be much easier and I just need to add some detailed information to my thesis, which can make it more reasonable!

Lack of Art Gene. I envy those who can sing well. I was not born with music talents and it is difficult for me to sing in tune, although I love music so much! I always treat music as the best way to express our emotions, especially when some rythm can perfectly fit your mood. But as it is, I want to throw my phone away when I hear the recorded songs that I sing following the origionals. Haha, it does not have a special case up till now. So, I think it would be better if I learn some singing skills, which could cover the lack of inherent talent to some extent.

Are you busy everyday? My roommate has been snoring about 10 minutes ago. Sometimes I admire his idle status and it seems that he does not have much work to do everday. I just finished a project proposal, wich is only a draft one, and I have to make some detailed revision in the next few days. How I wish I could had enough time to do what I want, regardless of daily grind. Tomorrow I have to go to the lad to process the test data again and then start to write the last chapter of my thesis. Hopefully I can finish it before May!

End of a relationship When I woke up and turned on my phone this morning, I recevied a message from a female friend. She sent me some pictures of chatting history about she and her boyfriend. I browsed the pictures quickly and realized that there is a big problem between them. Her boyfriend did not reply her message at all, even though she had sent dozens of text, video calls and phone calls. She told me her boyfriend had been such heartless since a months ago. Their current relationship really suprised me. Both she and her boyfriend are my good friends and we have been knowing each other for more than ten years. Six months ago, her boyfriend had been in American to attend a one-year-PhD project. She actually worried about the long distance at first, but her boyfriend gave her a promise that he would never betray her! Now, it turns out that he has totally forgot what he promised and is going to end the relationship by using unresponsive tricks! I think he has got the wrong idea and should has been acting as a real man to handle the problem. But now, he has become a coward and hurted the girl in a extreme way!

A small scar on my face There is a small scar under my nose, but you will not notice it if you don't stare at my face carefully. My mother told me that it was because my father's bike fell on me and the handlebar broke the skin, when I was three or four years old. But I don't remember anything about it at all, haha! The reason why the bike attacked me was because of my greedy. You know, my dad normally bought me some delicious food after work and then put them in his briefcase, which just hanged on the bike. So when I was trying to catch the briefcase, I pulled down the bike on myself! haha, what a greedy, stupid little boy I was!

Rape Flowers The filed of the rape flower on campus has become a scenic spot again，because rape flowers have started to bloom in spring. Most travelers are the local and most of them are coming for taking pictures of either people or flowers. Only a few students go for the spot since we can see the view almost every day, except for some girls visit there specially for selfie. Everything would be perfect if no one damaged the plants! Sadly, I noticed that some people entred the flower field in oder to take better pictures. They spoiled the scenery!
