Hello Hsjxhhdjdjdj
Friends influence our behavoir because we care about what they think and want to impress them. This can be both a good thing and a bad thing, depending on who your friends are.
Our parents influence us because they are in charge of us and have the power to give us good advice or bad advice. Same thing goes for siblings, teachers, and society.
I am not sure how the expectations differ between male and female. Both have huge exceptions from society.
Hope this helps!
