College bunk beds, upper bunks down, such as the water toilet bunk you will be with her every time

You should speak, the dormitory is like this, you have to look at the problem from the other person's point of view, and you will know it by empathy.

No, it's all bunk beds, just treat it as your own family, and you talk to your parents or brothers every time you see them at home, definitely not.

Not necessarily, living together will be very casual, you don't have to worry about those etiquette, classmates will not think that it will be rude for you not to greet her, roommates are like family together, it will be easier to be casual.

Needless to say, think about it, if you say two meaningless words every time, you don't get tired, and others will think you're verbose.

You can say what you want, and you don't have to please her.

No, people who keep talking to you are still annoyed.

I'm familiar with the dormitory.,There's no need to deal with each other again and again.

Just nod if you don't have anything to say, it's polite to do so.

I don't have to say it every time, it depends.

A simple greeting is also a good way to enhance feelings.
