Do you know, what is the difference between a girl friend and a wife?

Once, when I was sitting in my office cafeteria with one of my friend. We were just enjoying the time with talking to each other. Suddenly, my friend ask a question to me, Dinesh, What do you think that, what is the difference between a girlfriend and a wife? I thought a while, nodded my head as a thinking style, and said, both have a lot of differences. Wife means, responsibilities, scarification, surrender, and there is no opportunities of changing, while, girlfriend means, minimum responsibilities and maximum enjoyment and there is no scarification and no surrender. And you have also a lifetime opportunity of changing at any time. I just explain:

Girlfriend is like a rose’s flower, which is growing in garden and attracting to people, and they are admiring to it, and want to get it. This is called girlfriend. But, wife is: suppose that rose’s flower has been plucked from the garden and given to someone. Then what he will do, after a short while he will be getting bored. Now, he will have to be taken care of that flower for the whole life. This is called wife.
Couldn’t understand? NO PROBLEM, this nice story will tell you each everything about a girlfriend and a wife…….. 
