Every time you interact with others, you have the choice to listen to, acknowledge, and let go of their words, or you can take what they are saying personally. Taking things personally is often the result of perceiving a person’s actions or words as an affront or slight. In order to take something personally, you must read negative intent in an individual’s words or actions. But what people do and say has no bearing upon you and is usually based on their own experiences, emotions, and perceptions. If you attempt to take what they do or say personally, you may end up feeling hurt without reason.

I am one of those people who doesn't take things personally, for the most part of course. It's the "He's just not that into you" mentality. Very freeing - if you put what people are saying on them instead of internalizing it and making it about you, you'll feel much less bogged down by other people's crap!
