When I studied in 3th year, I get accident with my motorcycle alone at in Takkasila dromitory area because I'm careless and very hurry to go to BanSong school for try out information in evaluation crouse. I'm worry about I will late to go there so U'm very hurry to and rode my motorcycle very fast. I think it's not worth for risky with my life. If I ride my motorcycle for carefully, the accident not happen.
