This belter of a human passed away a few months ago.
The hero was more than a mere teacher to me. I have never met a person so inspirational; I got crushed under the wheels of a truck once in 2004 and this lad actually phoned me up (Nokia 3310) and sent over DVDs. The little things mean a lot.

If there’s a heaven, and I fucking hope one exists, this bloke will be up there. He was a polymath teacher who had the rare ability to combine charisma with intellectual prowess; he structurally broke things down for students and demonstrated how things worked.
Best teacher I’ve ever had. He was so smart and his accent was nuts! Every single pupil at Edinburgh College was blessed by his utter selflessness, his empathy, his awesomeness.
He was an incredible person and everything he said and did was right.
I’ll never forget you, pal. X.
