I went to the doctor and he told me I broke my ankle.
How did you break your ankle?
I got into a fight last night and fell
You should not be fighting because as you see you can be seriously hurt as a result. It is wrong to fight. Next time you could be hurt much worse.
I'm gonna tell everyone it was from a break dance move to downplay the seriousness of the situation.
That's fine, but it's okay to be honest about the situation. You should try to avoid getting into fights though in the future.
