2 weeks into my new company and this old dev wants me as tutor already.

Feeling blessed yet stressed.

If your lucky that means he is smart and knows that every new acquaintance is an opportunity to learn, and the best part of teaching is that the teacher often learn more than the pupils unless they have taught the same a dozen times already.

At least that is my experience from all the times I have taught things.

I end up learning moe on the subject to.
