I think it was hardwired into me at a young age at school - that it's important to be a "good" person and help others. I don't remember my parents telling me that but my dad is a very considerate, giving man so he probably set me that example.

Later on, I think I realised that it makes me feel good too and later still that yes, I think there's a certain amount of truth in the idea of karma.

So yes, I would definitely help people out if they were short of cash at the checkout. I'm also conscious of setting my girls a good example. The other day, I saw a woman parked at the side of the road with her hazard lights on. We went back to see if she needed help.
