Privacy

It's a big deal. You should always allow your roommate to have some time to themselves. Don't stay there 24/7. Maybe they want to have a "special" night with a significant other, maybe they need time to study, or maybe they just need some time for peace and quiet and reflection. I think that should be a mutual agreement really. Be considerate. That's what it's all about.

Eviction

I think that it would be common courtesy to let me know if you're not going to pay your rent.  At least I would be prepared when the eviction notice is posted on the door.  I'd like to be there so at least they won't take my stuff too!  I think it only makes sense!  When you live with other people, you have to learn to live with them.  You can't just do what you want anymore!  You have to start caring about other people.  You have to be able to compromise and help out.  Next time you decide not to pay your rent I'll kick your stuff out on the street myself!

Don't Sleep on the Floor in Front of the Door

Well...actually...I think that this one is pretty self explanatory!!

Pets

How about you don't get a cat that digs in the plants and uses the bathroom in them and plays around all night with a bell around its neck, without asking me first??  All I ask for is some respect and input since we both live here!  I'd never get a pet without asking you.  See?  I have some consideration for you, but you have none for me.  That's not fair.  Just don't ask me for money to help you take care of that brat because I ain't doing that.  Never!
