Now this is perverse. "Troll Craigslist (carefully), and you'll find no shortage of couples soliciting strangers to split the rent with them." Eww! The couples get a single to move in to share the rent and next thing you know? "Sometimes it almost feels like I'm in a relationship with their relationship," say the singles. Annnnd guess who's getting kicked to the curb the second that someone gets pregnant? (Ha, particularly if it's you who gets pregnant, relationship-intruder.)
