Lucky to find my bike back

Last week on Friday night, after i had party with my teacher at school, I rode my bike as usual to lead my dorm. It was really ashamed that i parked it in front my dorm and i forgot to lock it and then it was stolen immediately......so sad...i love my bike so much. But this week yesterday i finally found it back while i was walking home. I was so surprise who took and parked it in front of Seikyo(school cantine). I was on the cloud nine and i quickly rode it home. After arriving home, i started to think that i should have waited to see who took my bike.....I was so lucky anyway. I have to be careful and lock it every time.
