I was a little tired today, for I chatted with my friend on msn last night.We chatted a lot, such as our homework, future,and how to keep in good mood everyday. Sometimes, I think that why I am a human. Being a human is too busy.However, I have to considerate about everything when I grow up gradually. Can I be a tree if I can choose my life again? I think being a tree is much better than to be a human. If I am a tree, I can always stand at the spot and do not have to worry about what will happen, just stay at there.
