One time on the way home from work I stopped by the liquor store to get a beer, I buy my stuff and when I came outside there was some guy standing out there by my car. He says Hey homie, how'd you like to make sum gas money? I said I would, but I have to be somewhere right now. (even though I didnt). He then tells me that he just got out of jail (which was down the street, so that makes sense) and he needed to get to the next town over. Long story short, I'm glad I didn't say yes.. He could have killed me or something and took my car, he gave off some bad vibes.
One time when I was a teenager, me and my friends picked up a hitchhiker. He was a harmless looking old man who just wanted a ride to the homeless shelter. Anyways he was completely out of his mind. On the way over to the shelter he offered us all high paying jobs in his corporation at one point. After that he was so happy to see his son, who was my friend in the back sitting next to him. After he just started making random sounds until we finally got there.
