Ah, the red flag. Red flags, where dating is concerned, are generally warning signs that somebody is going to hurt or disappoint you down the road. Some of them are universal, like a person who is perpetually unemployed or talks over you. But some people have their own, personal red flags that have never failed them. For me, it was avoiding people who go to Burning Man and comedians. Has worked great so far. Twitter user @MichelleHux decided to ask her followers to share their own personal red flags – and they came through with some solid rules. We just feel bad for anyone who identifies themselves in the replies.
