After a month that has felt like a year, I took my sister to meet a potential new roommate. I'm not sure how I feel though. He is a man and he is in his late 50s. I don't have any bad vibes about him and we saw the entire house and there were no signs of a torture chamber anywhere. Positive note, he lives literally down the street from me (like a few houses down) and we live in a nice neighborhood. I still just don't know how I feel about her finding her roommate off of Craigslist.
