He was just the ticket for a Monday / first day of the week he could always be relied on to be much grumpier than anyone and therefore able to turn everyone around.
he had a presence (as most mentors do)
he taught me many things too many to mention but the most important of all was how to say No when stressed without swearing or rather it was that he helped me on my return to work after a total mental breakdown
Mentors move on - it's what they do - I'll miss him, sure, but now it's time for all his hardwork to shine through...I am now a well polished pleb
So Mr Stephen Sewell - hats off to you, you north eastern grumpy man - we'll stay in touch - but it's time for you to spread the "love"
