I'm going to make a joke to my friends sister about her fracturing my finger
How did that happen?
I was joking around with her then she punched me in the arm really hard, today after 3 days I have a fracture.
Ouch! I expect it was an accident but maybe not something to joke about.
Yeah, I'll be careful next time and I'm doing it to get my friends sister to like me.
Well, maybe don't joke with her if that causes her to punch you. Try finding something in common with her if you want her to like you.
