Overview
If you have to spend time with someone who you don't really respect today, try not to be unfriendly. Smile and treat them the way you would like them to treat you. Kindness is not only more polite, it is smart. You will get a lot farther if this person has good feelings for you than you would if they thought that you're always rude to them! Show them that you are a person who is good to work with. Show them you're respectful. Get the last laugh by having them help your reputation grow.
