<human>: Could you distill the essence of the text into 1-3 sentences?

I was walking out of my local store when I heard someone yell hey!, did you go to blah blah High School. I said yeah, I don't remember you, what's your name? He says Dave ****. I instantly remember his name and then I recognized him. He says, you want to make some quick cash? I'm in a bind. Gullible me says yeah, what's up? He says I got to meet this guy and pick something up. Ill give you 50 bucks and it'll only take 20 minutes. He asks for my number and I give it to him. Say's he'll call me in 10-15 minutes. I remember Dave as a decent guy from school and we hung out in childhood, however; I didn't know him in high school.  He calls and says meet me at my house, which is only a few block from my house. So I go pick him up and he tells me how to get where we're going.  

He tells me that guy lives in Southwest Detroit, which isn't the best of neighborhoods. I say to Dave, what kind of shit are you getting me involved in man?. He says he's a caregiver for a medical marijuana dispensary and he has to go buy some seeds. Tells me everything is perfectly legal and he has a caregiver's card. A card I didn't bother asking to see. So we go to the neighborhood in Detroit which is less than 15 minutes down I-94. We get there and Dave tells me stop on the side of the road after pulling off a main road. Guy #2 pulls up and Dave gets out and does the 'deal'. Dave gets back in my truck and we head back to the burbs. I pull up at his house and he says thanks man and hands me 50 bucks. He says there's plenty more easy money to be made. I drive away wondering how I got suckered into some shit like that. The only kind of proof I have is that he was on the phone with the person he plans on selling the seeds to, and actually used the word seeds. Could be code for meth or crack who knows. 

Now Dave has my number and will likely be bugging me for future money making opportunities.
<bot>: Ran into an old acquaintance from school days. Dude lured me in with the promise of easy money for just giving him a ride. Probably contributed to the distribution of a hard drug.
