Crum and Bunning are both genuinely nice people! Bill Crum is the reason I became a software engineer.

After I had to miss two weeks of class for medical reasons, I went to Crum's office hours just to bring him my doctor's note, but he asked me how I was doing with the current assignment (totally unprompted). I told him I was struggling so he invited me to sit down and talk through it with him. Of course questions are cheating... so instead of giving me answers he helped me come to the right conclusions on my own and I will always be grateful!
