Usually you'd just pass these people by. You plan to do so, until the smoke hits your nostrils. You involuntarily inhale and, as soon as you, you start to reconsider. Would it really hurt to hang out with them for just a while? Hell, maybe even take a hit of green? It wouldn't hurt anybody, would it...?
You sit down next to one of the group and begin talking to them. As you shoot the shit with them you find that they're not the dumbasses you'd thought they'd be. You still think you're kinda superior to them, but still, they're somewhat competent to you right about now.
When the bowl comes over to you, you take it up to your mouth and inhale some of the smoke. You exhale quickly, a mix between a sputtering cough and a normal breath. You start to feel a little dazed in a good sort of way. You fail to notice that your originally neatly combed and cut hair slowly begins to change, the hair staying the same length for now, but moving out into an unkempt look. The group of stoners you're with all notice it, though, and smile.
You barely get enough time to talk to them. The minutes pass by fast, and soon enough the teachers are leaving. The group quickly disbands to their seperate cars, but not before their possible leader, this senior with a blond goatee and head of hair hanging down the back of his shirt, invites you to a small party the group is having between themselves that night. As you walk home and then get into bed for a short nap, you're highly interested in this party, and begin to work out plans for going to it.
