What is wrong with this person?

I don't know if something is clinically wrong or they just have their head in the clouds or are selfish or what...? Here are some observations I've had:

- Lack of emotional response. You show or tell them something expecting a certain reaction, and they just half acknowledge it and then change the subject. Like recently after showing them our new apartment renos "That's nice. So and so's apartment is a lot smaller than yours, but they've made it really nice and cozy. They passed by this weird guy in the hall... " etc. It leaves you feeling like they don't care about what you just showed them. Thing is, I think they do care, they just don't show it like other people do.

- Don't listen to you. You start telling them a story, then interrupt half way through with their two cents then continue to talk and change the subject before you can try to finish the story/thought

- They ask a question and then don't wait to hear the answer. "How are you? So and so said their coming over today..."

- They tell you these long stories about other people and wonder how they were able to listen to all this. Is it just us?
