My dad is a teacher and teaches others so they acquire knowledge
That's awesome. What subject does he teach?
third grade but anyone can be an informal teacher
Did he have to go through any special training to become a teacher?
Yeah dad has a degree but in some countries its very common to teach at home instead of a formal setting
I was home schooled when I was younger, but I didn't like it.
Certain other professions involve a fair amount of teaching
Really? Give me some examples.
