How do we view ourselves?

In Soc we talked about how the public generalizes genders. Yet we are taught from a very young age that girls are supposed to be thin, pretty, and flawless. We spend so much time only learning about the feminine generalizaton that the male generalization slips our minds. Sometimes we take it for granted that guys just come off more tough, or less talkitive than girls. Thats why I found the first movie about generalization of guys to be very intresting, and when I went home to observe my little brother to see if he fit the part, I found that everything the movie was telling me was true.
He tends to play with nerf guns all the time, which at first I thought meant nothing. Then I started to realize that everytime he was holding the guns or playing with them his language would become meaner, as well as his attidudes towards certain things or people. Yet when it was just me and him, his more feminine side started to show such as politness seeing that I was not a person who he had to prove himself to.
