Now I know that you will probably think I have gone a little bit mad with what I am going to talk about today but if you bear with me and keep an open mind I am sure you will find it interesting.

I can remember being with my dad when I was younger when we were queuing up in the supermarket. There was an old lady behind us who was buying some dog food and she was carefully counting the money from her purse to pay for it. She didn’t look like she had much money and when my dad came to pay for our groceries he gave the shop assistant another 10 dollars and said he would pay for the old lady’s dog food.
