One of my colleagues is too harsh and likes to haggle over every ounce. What should I do?

To be tolerant of others is to be kind to yourself. There is an interest relationship between people, because everyone has selfish desires. Who doesn't love himself? Is everyone on earth like this? As long as you have a tolerant heart and don't haggle with others, how can others give you a hard time? Learn to forget, remember in good faith, be good at forgetting others' bad things and remembering others' good things at work, so that you will have a beautiful heart. . . .
