I once broke my foot whilst walking on the side of the road by twisting my ankle in a pot hole. I was lying in the road in agony for about 30 minutes. Every single Thai person drove past me, whether they were in a car or on a bike. The only person who stopped to help was a german guy named Hans. He drove me back to my house and I invited him to stay for dinner, to which he politely declined. He helped me with my bandages and asked do I need an ambulance, to which I told him not to worry my as wife will be home soon.
Make of that what you will.
