Actually, a mentor asked me this question. She has been mentoring someone for about 2 years and has come to care about them – even though they only meet a few times per year. She knows her mentoree is having some personal upheaval and has become withdrawn. As a friend, she might reach out and offer her help. As a mentor, she feels compelled to stay away.
She doesn't want to make anyone uncomfortable or embarassed as she feels she holds some power as the mentor.
What would you do in her situation?
