Yepper, I am also rat friendly. I used to have them as pets before my last attempt at college. My pet rat would actually determine if there was a second date or not based on the reactions of my rat and date.
One time, a rat moved in with me. I saw it sitting on my kitchen counter as I was on my way to work and saw that a hole had been gnawed in the wall above the sink. Came home that evening and did the damage assessment and saw that the only thing was the hole in the wall. The rat had not gotten into anything else including food, so I just figured 'live and let live.' We developed a routine each day that involved my coming and going to work each day. Every morning, the rat would be waiting on the counter until I went to work and said "I'm going to work." Then it would scamper back into it's hole. Every evening, it would be waiting for me to come home and say "hi, I'm home" then it would go back into it's hole. This went on for about four months until it got particularly cold one night. I was sound asleep and then I felt something warm and furry curl up by my shoulder and neck. I quickly turned on the light and saw a brown blur racing towards the hole in the wall. I said "I don't mind sharing the house, but we aren't sharing beds." After that, I never saw it again.
