In this world every body owes something to others and someone owes you also. This is nothing but the life. To survive in this world we have to ask something from other may be some money or help or something else which we does not have or which we cannot afford to have it.
But as human being we all have one common tendency as such in this case. You may say that you do not fall in this category. But you are falling in the category I am talking about. Hey, nothing serious or bad to think about, it is just overall circumstances that us happening in the society as whole.
When we owes money to others we feel that time has comes too fast to repay the money or many time we try to five some excuse or try to give some reason in delaying their payment. (I am not talking about paying the installment to bank or any Financial Institutes). But if same excuses other person (Who owes us the money or who had taken money on loan from us), we does not like other person such attitudes of not keeping their promises.
So keep in mind that first of all you be the perfect in your act, and then expect other to be perfect.
