Share your thoughts with someone who has frustrated you a lot lately, and see how they react to what you have to say. Total honesty is required if you want to do this right, so don’t be afraid to fully disclose how you’re feeling about them or about what they did. The sooner you do it, the sooner you’ll know what’s next for the two of you. Now is not the time to pull any punches. You don’t have to be confrontational; you just have to be firm.
