I work for a charity and last year I took a group of volunteers to Africa.
As we drove down one street, a couple of the volunteers started crying "Look at all the poverty, poor people lining the streets, begging for scraps of food and robbing each other just to get by. I don't know whether I can go through with this."
"Don't worry." I replied "We'll be on that plane and out of Birmingham soon, things won't be as bad when we get to Africa."
