First Day Of School

A day of school that looks anxiety producing and scary, but in reality isn't that bad.
Me in August: Noooo, the First Day Of School is in less than a month now! Homework, stress, 10 months of torture!

Me at the end of the first day of school: Huh, that was easy. There's no homework until a month from now. All I had to do was introduce myself.

Marin Country Day School

A bunch of rich kids that walk around and act cool but are not. They cry when they get below a 90% but laugh at other people when they do badly. Everyone is very insecure and has a wide range of problems. There is a no-bullying agreement that never is looked after and is often broken. While some kids talked about regular things, people from MCDS discuss their future carriers and talk about how many phones they had. MCDS prides itself on being a sporty school, but we have never won a single game of basketball because we are all really bad when it comes time to play. Countless boys pose as a skater but have never touched a board in their life. The few people that do skate go hardly noticed because they are usually the unpopular kids and no one cares if they do, but if one popular kid touches a skateboard people automatically think they are going to the Olympics. IF a girl does not bring there pumpkin spice latte to school they will suffer from extreme withdrawal and go home to their 30 million dollar house. There is 0.01% of kids that go to MCDS and are not complete dicks. And those kids are the people that leave the school after 1 year because they have been bullied into leaving.
