Hey, I learnt a very large amount of stuff from that old man, some of it good, some of it bad. My trick in life now is to make sure that differentiate between the two and make sure that I expand of doing the good stuff and avoid doing the bad stuff. Nodoby is perfect but if I didn't learn anything from spending 8 years or so in his company then that would have been a decade of my life wasted.
And I don't like wasting time, there are too many bikes to be ridden still.
