A funny story

A man was boating of secret how to keep family happy. He said to his friend at a bar: " At home, I make big decisions and my wife makes small ones. So we never use strong - words". "What small decisions does your mother decide?" asked a friend of his curiously.
The man cleared his throat and said "She decides what to eat for meals, how much to save money a month, where to send my kids, what household I have to do, where to spend our holidays, whether to buy a new car and small thing like those.
All of his friends asked "What big decisions do you make?' The man said slowly "I decide who is the US president, whether to send man to Mars, what to do protect the Earth again being from outer space and great things like those".
