Why Not?

I am known as a somewhat odd chap sometimes. It seems to me that it is because I don't tend to ask why, but why not!
After all, there is no really good reason why we should ask why? Whenever we do something, we go with "why should I do this?" So why not use "why not do this?"
It gives you very many choices. And lets you do things you might never have done if you had asked "why?"
Of course, howling at 1:00 in the morning at the local stray dogs at kharagpur might not seem quite so attractive, especially when the howler has a sore throat!
