So after a lot of thinking and weighing up the options fully, you've decided to buy a car. You've wanted to buy a car for ages and you've finally found the one for you. It's a silver Mercedes and you love it. It is a pleasure to drive and you love being seen with it. In short, it is everything you could want in a car.
However as time passes, you decide you don't like the Mercedes anymore. You want a Jeep instead. So, do you think carefully about your decision and decide you want to keep the Mercedes or do you take Mercedes back to the shop for some else to buy and enjoy.
You do neither of those things. You decide that it's the Mercedes that has to change. So you set about pummelling it with power tools, welding gear and scrap metal. However much you try, the Mercedes doesn't become a Jeep and the more force you put on it, the more of a mess it becomes.
Until all you're left with is a wreck in place of something that once made you very happy.
There are some things which cannot be changed.
