When you're angry with someone, do you let them know or not?

Do you let the person know that you are angry with them or do you just keep it to yourself? If it's someone close to me, I will let them know but if it's someone that I'm not close with it's unlikely. What about you? Also, do you think it's best to let someone know that you're angry with them because if you tell them they might be become scared or afraid of you.
