Tranquil life

I am busy in my lab, and I have continued two days to do experiments for more than four hours. Frankly speaking, it is a little tired to sit in the small room such a long time. I felt my neck pained and uncomfortable during the process, however, I think it must a necessary stage for every beginner to practice. I killed two mice to acquire their thighbones, so that I can extract their marrow stem cells to cultivate in cell culture flasks. Because the whole process must under the aseptic environment, the requirements of techniques are high. It is the first time for me to accomplish the whole experiment by myself. I successfully got four flasks’ cells at last, and I hope they can grow healthily in my great care for them.

The mouse cried when I pulled their heads to kill them this afternoon, which made me still a little uneasy. I think I should thank all mice which devote themselves to my experiments, because I can’t make any improvement without their sacrifice.

I felt a little relaxed these days. Though I still remembered him a little sometimes, but it was not the extent to miss him. I don’t worry whether he is happy or busy any longer, nor expect him to call me or visit me any more. My feeling suddenly becomes calm and I have time to plan my future about furthering my study or seeking a job some years later without considering him. I sincerely treat everybody I met in my life, including him I once choose to like. Therefore, there is no regret or pity in my mind. I have strived to maintain our relationship in the past all after.
