You could tell he was a very influential teacher because he would constantly get visitors that were previous students of his. In fact, I've been back to my high school a number of times just to visit him, and I know many of my classmates have done the same.
There will be a retirement party for him in mid-June back in Calgary (my home town), and I'm contemplating going back for it. But, with the house and other stuff going on, I'm not sure if I have the time or the money. Granted - if I do go back, I'd get to see my family too, which is always a bonus (right parents? :D). Hmm...not sure what to do!
