I'm a little nervous...

I went to Yuba for the weekend. I got home about 1/2 an hour ago. I'm just a bit weirded out that I have a roommate now. His toiletries are in the medicine cabinet, his room is all set up and he has food in the pantry. I'm nervous and antsy about having a roommate. I don't want one at all but it's a necessity. It's weird to have a man around even if he's not here right now. I hope this works out ok and I can handle it. I'm not always to good at sharing and I just don't want to share my space. Now I have to be sure to be neat and pick up after myself which I'm also not good at. I'm trying to look at this as a lesson...
