If you hate going at it alone, whether its out and about at social events or smaller trips to the mall or movies, you no longer have to. RentAFriend.com boasts 526,873 friends available for rent worldwide (as of February 2015). While it might seem bizarre to pay for a perfect stranger to hang out with you in your downtime, renting a friend can prove quite practical in some instances. When moving to a new area for example, a rented friend might be able to provide a better lay of the land as well as make some useful introductions to other locals.
