“The sooner temper shows up in a relationship, the worse the implications. Most people are on their best behavior early in a relationship, so be wary of people who display irritability early on. It can indicate both brittleness and a sense of entitlement, not to mention disrespect. People who have a short fuse and expect that life should go according to their wishes don't make for good company. If you find yourself reflexively stepping in to soothe someone's anger, watch out.”
