Input: So, I was gonna get a single dorm, but my parents thought it was too expensive, so I got a double with a randomly assigned roommate. He was a bit awkward at first when I first met him and he didn't talk much. I noticed he had some kind of animal costume in his closet one time and thought it was for Halloween or something. Everything was generally okay up until the point he talked to me about "furries" and I thought it was alright, not for me, but do your own thing, you know? After this however, he started wearing it in the dorm while talking to his friends online. I usually have headphones on and our desks are facing away from each other, so it didn't really bother me too much, it was kind of weird though.
Anyways, I told him I was gonna have a friend over to do calc homework, so I figured he would take off his fursuit when I went to go down and let my friend in, but when I opened the door, he was standing right in front of it and said something along the lines of, "Hi X's friend! I'm Y, his fuzzy roommate!" I was shocked at this display, I saw my friend looking wide eyed, not knowing what to say, so I just said, "we'll be right back" and we just went into the study room down the hall and just pretended it never happened. I had no idea how to address it in the first place. After that, I went back to my dorm and told him that it seemed a little much to do that kind of thing in front of strangers and he said okay, but he seemed very sad, so I assumed he got the message.
Unfortunately, he did not, and when I told him that a few friends were coming over to watch some videos, there he was again, but this time he was sitting at his chair and just said, "Hi." It was an improvement, but he was still wearing his fursuit... I just told my friends it was for some kind of project and shrugged it off. We were watching YouTube videos on my laptop for about an hour and throughout that my roommate was talking to his friends quietly and would occasionally make strange animal noises and my friends started glancing at him.
I didn't know what to say to him after my friends left, but this has got to stop. I don't know if it makes him feel more at home to wear his fursuit, or if he's acting differently because he's in a new place? I just don't get it and need some help getting him to know that he can't wear his fursuit while I have friends over, but I don't want to hurt his feelings. What do I do?
