How is age an appropriate excuse to my concerns? My concern is that he can't be transparent and open - meaning his thinking and behaviour will be molded by this. People clearly want to hear the truth out of his mouth, he's a coward - he's afraid of the ramifications of sharing the truth. He hasn't shown he's grown up. If he wants to lead, becoming skillful at self-awareness/growth and relationship building is key.
