Why Do Men Hate Shopping?

Let me just say something that I could regret later:  I love shopping.  If I had the money, I would be buying clothes, shoes, and video games everyday.  So, why is it that when I go shopping with a girl, they also accuse me that I hate to shop??  I always have to have a girl shop with me when it comes to clothes.  It is essential.  I'm so afraid that I'm going to end up buying something that's going to look horrible, and my past certainly proves that.

So why is it that every girl I go shopping with, accuses me of being "bored", "tired", or "not fun".  The truth is, I don't like to just sit, and debate, and wonder what I'm going to buy.  I like to find what I'm looking for, pay for it, and move on.  I guess you can call that "UN-shop-like", but to me, it doesn't mean that I don't like to shop.  I just want to take care of business and move on.

Does this sound like a guy who hates shopping?  I know a lot of guys that are in the same position that I'm in.  They love to "shop", just not as long as the ladies.
