Lonely Planet

I have been in this work for a while now - so much so that I am readily accepted as an old timer. I have seen many come and go and it never bothered me so much as it did today. The guy who I originally started to work for quit, after years of service for the company.
I never thought attrition would bother me. I have seen people quit after a week, months, years. However today was different for me. I felt like I have lost a great supporter, mentor from my professional life. Working will be different, approaches will be different, hell....lunches will be different this point on.
