I know an example with many women is if greeting them, they would just ignore him. Besides being rude, that is also stereotyping, assuming, and paranoia. It is that all men are just after one thing - to get her in bed. Oh well, don't assume, it makes an a s s out of u and me.
It can also be the influence of mainstream anti men feminism.
With many women, if a man does or says something to her that she doesn't like or agree with, then she'll want to hold it against him for the rest of her life.
There are times when a woman will either want to jump into bed with a man, or else not want to have anything to do with him.
Some women also would show an interest in a man, and immediately assume that he will reciprocate. If not, then will immediately assume it's because of her. But, maybe it's because he is shy, emotionally inhibited, doesn't want to be unfaithful, and so on. Thus, being cold.
