What personality trait in people raises a red flag with you?
Instantly, I can feel out a persons true self no matter how determined they are in attempting to hide behind their facade. Liars are easy to spot and are, of course, high on my list. But someone who is unable to show empathy for another person or animal, I have no patience for, nor do I want them in my universe of those I consider friends and loved ones. Those types of people can suck the air out of a room with their stifling negativity, which is detrimental to anyone who dares to try and breathe said air. Please, do not give them your precious time or attention.
