Have you ever considered someone to be a good friend, only to later realize you didn't know them at all? It sounds like something out of a Lifetime movie, but it happens more than you think.
A recent Ask Reddit thread has people sharing the moment they realized their so-called friend was actually a terrible human being. Some are shocking, some heartbreaking, and others downright illegal.
Some poor lady fell out of her wheelchair, I turned to see my best friend absolutely losing it laughing.
When he got my sister pregnant... a month after he got my wife pregnant.
when she told me a game she played at house parties was just to steal random things. she would take people's remotes, forks etc.
