Can I ask a few questions about women?

Before I start. These questions do not pertain to all women just the majority I have seen while living in NYC.

1— Why do some women/girls get angry when they don’t get attention from guys? I have seen many women/girls get angry when guys don’t give them the attention they want or feel they should get. As a guy I know not everyone women is going to like me.

2— Why don’t many women/girls approach guys they like or are interested in? I have noticed they stare at the guy and try to get their attention. Many times the guy does not notice them. Why not just go up to the guy and talk to him.

3— Why do many women/girls feel or think every guys likes or wants them? Some women/girls are so into themselves. To the point that they think every guy wants them. In NYC I see that a lot.

4— Why do some women/girls feel the need to look down on other women/girls just to make themselves feel better? Every women/girl should love themselves. However looking down on others is not a good thing.

5— Why do many women/girls feel all guys are the same? Many think that all every guy wants is sex and that is it. Which is not true all.

Sorry if my questions come off as ignorant or whatever. I am just interested in why some women/girls do these things. I am not trying to offend anyone.
