Helped a guy who was an acquaintance, who I thought was a friend move into my apt while in grad school with my other roommates, vouched for him, paid his part of the security deposit too. He turns to be of the kind who talks behind the back, borrows without repaying, a general douche.

Long story short, months later, said guy moves out. Lost my money, lost my other roommates, and lost my reputation as a guy who can vouch for others. Lesson learned: takes years to know a person.
