High School
(Strange Things Students Have to Put Up With)
1. Different Kinds of Teachers: Some are unfair, some are really nice (which I don't mind at all), students eventually learn how to deal with the "rules" of each teacher depending on what type.
2. Different Kinds of Schools: Some start later than others or let kids out of campus during lunch. Some let you slide when you mess up, others punish harshly.
3. Different Rivalries: Some school vs. school rivalries are just friendly competition, some may need the Wall of China between them.
Different Everything! It would be better if the rules were the same to everyone, then there wouldn't be so much complaining!
