Public displays of affection (or P.D.A) on campus can get crazy at times. People making out every corner you turn to can get disturbing. A peck here and there should be fine; anything further then that should be behind closed doors. Things like that should be hidden not broadcast to the whole student body!
I understand teenagers have their urges and feel the need to show them, but on a school campus is just wrong. I bet you feel the same way if you see someone making out with their boyfriends or girlfriends. You might even start calling them a few names. But for what? Doing the same things you do?
Trying to tone it down is not the hardest thing you will ever do, but I know from personal experience that it’s not the easiest thing ever. But it’s possible. Do it for the safety of your reputation, because doing stuff like that doesn’t bring the best rep. Unless you want a bed rep, take my advice and maybe just tone it down a bit.
