What is your favorite high school memory?

I just started high school and it’s okay. However, it has its flaws, like most schools: The building has been around since the mid ‘70’s, the classes are harder, and one of my friends left( cough, cough, jellyfish3232). They say we will make life long memories, but I couldn’t imagine what kind. So, what is your favorite memory of high school? What did you like/hate the most?
