Did Lot of shopping and feeling so happy..!

Just a thought why shopping gives so much of pleasure.. Because in life mostly decisions are taken by others, like parents or destiny. From birth till marriage (which is almost like a death....of a bachelorhood :) ).  But, there are few things which you can decide like you want to buy a shirt or T-shirt, color, design , shoes, Jeans. It gives you a feeling that still you have control on your life and you can yourself decide it.
