I find the process of hitchhiking interesting. They use different methods of signaling drivers all around the world. Have you ever hitchhiked?
I have hitchhiked once from New York to Chicago.  Have you?
That's really cool! I actually have not. What method did you use to hitchhike?
The good old thumbs up and a sign that said New York to Chicago.  I was lucky in that it was an elderly couple that took me in.
How neat! Did they give you the whole ride or did you have to switch off?
They gave me the whole ride.  They were getting off around Chicago which made it perfect!
That worked out perfectly! Did they ask for any compensation?
Nope, given that it was an elderly couple on their way to Chicago, they were really nice about it!  I did offer to buy them dinner but they declined as they said it was the right thing to do.
