A person looks down on you? What can be seen from it?

Is a person looking down on you? What can be seen from it? I think it can be seen from the following aspects: first, when you are in direct contact with her, she doesn't even look at you, but squints at you from the corner of her eye, looking disdainful. Second, she won't even listen to your advice. Third, people often speak ill of you, saying that you are not good here and there, as if she were the only one in the world. Fourth, when we met, we didn't seem to see it.
