Have you ever been so wrapped up in how you think the world “sees” someone close to you that you were embarrassed by them? Hold that feeling and take the emphasis off of you. Now shift the emphasis on them. How do you think they felt or would have felt, had they perceived that you were embarrassed? Would they be hurt? Would they feel betrayed. Now you really have something to be embarrassed about.
My closest friendships all have one thing in common; all of these individuals bring out my best qualities. My standards are raised in their company. They challenge me, they push me emotionally, intellectually and/or physically. They force me to move outside my comfort zone and they elevate me to higher levels. And I doubt they are even conscious that they are doing any of this. That is just their nature.
