When I'm writing this, I haven't graduated yet, but the time it's published I will have. I'm not to Senior Week. I get it, it's a beach trip with all your friends before you head off into the real world (aka college) and an excuse to drink all the beer in the world, but frankly, I don't see the appeal.
You can go to the beach whenever with whoever you want. You can go to the mountains whenever you want. Everything that people do for senior week, you can do whenever you want.
Besides, it's stupid expensive.
You have to get a house to rent, buy food, buy gas. All that adds up real quick.
Senior Week isn't for everyone. If you don't want to, don't. I'm not. And I don't regret it at all.
