And this is what makes a child's heart the purest

The topic of utmost concern during lunch today was an ambulance stuck in the traffic jam. My kindergarten going son came a little late from the school today. When we settled down for lunch he said do you know why I got late today, to which i replied must be the traffic. He said yes and do you know what happened , " an ambulance was also there in the traffic jam and no one was giving it the way to move ahead", Then he went on and on about how people were honking their vehicles and nobody paid attention to an ambulance which was on its way to help the needy. He said that he asked his father (who picks him up from school everyday) why is no one giving the ambulance the space to go ahead to which he replied that they are not smart people, and want to move ahead themselves first. I wonder how to explain to a 4 year old the "don't care less" attitude of people,to let him know we preach but we do not practice.
As a child he has just started his social contact through school and witnessing such moments indeed confuses a child. Yes people can get away with any amount of callousness and he should learn it as soon as possible, but would it be the right exposure at such a tender age. The impressions on the formative minds makes me fearful of the implications.

The values and virtues we teach our kids are not actually imbibed by us. We expect a very high degree of morality from them, no lying, no cheating, no hurting others, no use of bad words, sharing, giving. On the contrary we tend to break queues and move ahead whenever get a chance, lie to each other as adults, cheat people, hurt with our words and  actions.
