dear babu, my contribution to india is great. i 'am un-married and decided to have only one child.i stopped using my bike and started using public transport. i stopped using plastic covers. i 'am paying 8500/- as income tax. you are saying that i donno how to behave with senior citizens. why should i behave good with them. i feel everyone is equal either he is a senior citizen or a 5 years boy. it will make any difference to me.
