Today, I had a very had luck. I was fighting for fun with some classmates after physical education. I wave my arm with such great strong that my watch got loose and flew off my wrist! Just then, some girls were passing by and a flying watch hit one girl's mouth exactly, these two teeth were knocked off. My mother was called in to deal the matter. We made an apology to the girl but took her to hospital to treat my wound.
I was teaching a great lesson in this incident. I shouldn't have been made sudden and strong actions. From now on, I'll take care to do anything, acting quiet and carefully!
