,y sisters friends act stupid what should i do?

Question

all the time my sister and i are around her friends they act stupid even in public. if we tell them they act stupid they take it as a joke.

Answer 1

Tell your sister to explain to her friends how they should act more mature, and stop fooling around. not rudly, but just let your sister's friend no that being loud and crazy outside in public is immature and not lady like. I don't know if there girls or boys but its not cool. If your the older sis or bro you could talk to them too. Or talk to their parents about their behavior.
