Approach people whom you don’t like tactfully.
We all have met those annoying individuals who just don’t understand the word “no” or behave in an unmannered way. Remember, you don’t have to be like them, as two wrongs can’t make a right. Ensure you are as polite as you can be and bear in mind that you have to be tactful and sincere in how you approach anything related to these sorts of individuals.
Just as Winston Churchill said, “tact is the ability to tell someone to go to hell in such a way that they look forward to the trip.” So be tactful in your approach.
