I did not find him particulary friendly,I would not be surprised if he used a cane back in the old days!I remember him getting angry once due to the fact we were not doing latin anymore,we thought it would just make things trickier,all latin basically seemed like was a language which had some words that sounded minutely like some english ones,he's not exactly the type of teacher I would want teaching my kids,I prefer genuinly friendly and caring people.
I have to say I found Jack very good advised me not to do honours English I ignored him ended up repeating. Found him very good accountancy teacher also SMcD
Have to say thought he was an excellent teacher although could have done with out the ear pulling. Good man Jack!!
Scared the daylights out of me many a time but we deserved it (maybe!). He knew his stuff and was quite an interesting man who took pride in everything he did.
