I would kick my sons arse up around his shoulders if he ever pulled a knife on someone. Just remember that what goes around comes around and I hope no one sticks you when you least expect it.
Believe it or not, your school years are just a blink of the eye compared to the rest of your life. But in that short time you're laying the foundation for who you'll be for the rest of your life. Don't waste these years worrying about silly stuff like hugs and holding hands. It means nothing in the big scheme of things. Just do your work and get through school the best you can.
And when you get out of there and move on , you probably won't see 99% of those school friends ever again. So please keep that blade in your pocket, or better yet at home. If you think school sucks, drive by the local state prison sometime. Gladiator school ain't no joke. If you screw up and get sent there you'll be praying to GOD that they do have a policy against showing affection.

but you know whats sad.... I never really believed anyone when they told me this, but now I have 38 days left in my high school career and I am wishing I had done less stupid, more intelligence. less bullying and more love. This senior year for me has been more real world educational then book educational just because at my school senior year is your year, your make your schedule, you do as you please, but consequences are still swift and hard. you dont like? Heres the door, dont let it hit you on the way out. I remember back in 9th grade I was busted for selling weed. I made a joke of it then because it was "cool" to do. now looking back and being a certified EMT, I realize just how stupid it was. I look at my high school transcript, and kick myself in the bellybutton because I was denied the one school I wanted in to.
Stealth, I don't know what grade your in, but take what uptown said with a grain of salt. I reckon your a junior or senior which means you arent far behind me, but it always seems a peers insight means more then a grumpy old man who doesnt know the first thing about living, right?
And to Ripley, not looking to start things, but look at my posts here. my grammar, spelling and mechanics are sh*t. anything school related or something I should be serious on, I use the best grammar spelling and mechanics I can muster. I hope Stealth is the same.
