I have had a very good boss quite a few years back. I had a tiff with him and had to leave the company. Down the road, I realized that I was absolutely wrong and I could have handled the matter in a better way. I want to apologize to him and request him to be my mentor. Edit: I am planning to send him an email regarding the same. Should I send him an email or should I take a telephonic appointment with him? What would be appropriate?
We live in different countries. So, the communication would be through e-mails, mostly.
