When we judge a person, we are likely to think about whether he or she is keeping promises, the person who always keeps his promises is popular, people around him are willing to make friends with him. So keeping promises is very important, we should never break our promises, or we will be abandoned by others. First, we should never late for meeting or date. When we make a deal with others to meet at some places, we shall be there in time or earlier, it is rude to be late and let others wait for a long time. I hate my friends late for meeting, though they have reasons, they could have been here in advance. Second, we’d better think twice before making a promise, if we promise people, it means we have ability to finish it, people are hold great hope on us, if we fail, how disappoint it is. So we should measure ourselves before we making a promise.
