how to live together with one who don't want to see?

aww.. my advice to you is.. don't hate that person.. cuz wat cud u do.. ur living with that person.. haha.. all he/ she cud do is make ur life miserable by just existing.. so.. learn to love that person.. :) goodluck

I would excuse myself politely and leave. There is no reason to speak with someone you don't want to associate with. Maintain your manners and dignity and just leave.

I would be very civil in facing her/him. I will answer her/his questions properly but I cannot miggle with her/him. Since I cannot stand having a long conversation with the person I don't want to talk to, as much as possible I would keep myself busy by talking to other people in the crowd or I would try to excuse myself as often as possible - such excuses will be I have to go to the restroom, I have to get something or I will just listen to my ipod. lol

If I rent a room in that house, I prefer to stay in my room. There might be some occasion where we'll eventually meet, I won't talk much in such situation. After completing what I want to do there, I would excuse myself politely and went back to my room. Basically I avoid contact since I might show how much I hate to be around, which is impolite.
