and the reason why I'm not a Math minor...

Here's what my friend's math professor said to the class after a particularly difficult midterm:

I know I'm harsh and expect a lot. I know you have 3 other classes. But I had 6 other classes when I was your age. If I didn't succeed, I wouldn't get my scholarship, and my family starves. So I worked hard to feed my family.

And he wasn't joking.
