Don't listen to these grannies. Go party 'til you can party no more.
Just kidding yeah... it's good to have fun but, I know you, Riley. You're not like the other kids... are you sure you would even have fun at some childish party? Would you be constantly distracted by something that you couldn't explain to anyone else? Would you catch a glimpse of the sunset and wish you could share it with anyone around you?
The party mentality tends to drown out some of the aspects that I know you admire most in yourself. I could see you being the girl who always goes home early. Then again, I might be wrong.
It doesn't matter how you embrace those most wonderful years of your life. Personally, I'd spend them in preparation... give something back to the community... get involved in volunteer programs, spend some time with that sort of thing. When it comes time to apply for universities, THAT is the kind of stuff you'll look back on your childhood and wish you had done (TRUST me, that's what I'm wishing I'd done right now).
Don't let your social life bum you out. You're a poet, so naturally it's going to seem sometimes that you don't quite "belong." Just remember, there's nothing wrong with taking some time to yourself instead of partying, or doing homework... just take a walk in the park to let all that stress wear off... it might make you feel better.
Talk to you soon.
Poets are the unacknowledged legislators of the world.
