For me:
1. Too prideful teachers who cannot accept being corrected. Forcing that SHE is correct even though it's definitely, absolutely wrong.
2. Insecure teachers who, just because you always recite, say that you are "padayaw" -er, braggy, uhh.... giga, i-translate bi sa english ang hambog. (My teacher was like that and it's a good thing she was replaced.
3. Teachers who are very, very boring. Like in our geometry class. *yawnness* May sariling mundo yung teacher.
4. Those who always compare us with "better" batches of Special Science.
5. Teachers who expect too much from us, and think that we are just robots who don't need rest from all the homework and projects. (three difficult projects, one subject, due the next week)
6. And those who "dote" on you, even if you don't do anything bad.
