One of my theoretical CS teachers always complains and makes it sound like everything around him is an annoyance to his existence
- being late or in a bad mood? His pregnant wife is very tiring (good ol' haha women are hormonal much?)
- having to create and correct exercises for us (students) is a nuisance because it's so much work and we're not supposed to be spoon-fed (which makes the whole learning experience very demotivating)
- every explanation start is continued by at least 3 changes in the explanation itself, which makes everything super-confusing
- all his helpers are incompetent and not rising up to his expectations

Someone needs some self-reflection
