Just Boys Being Boys?

I did not have any brothers. Just the two sisters and me. We only had one boy cousin who lived close by when we were growing up. The result of this is that I don't really know a whole lot about little boys. I have been learning about them as my two boys grow up. Fortunately for them, they have their dad around to guide them in the ways of being a boy.
So, in not knowing much about little boys I often wonder if the things that these boys do are just normal little boy things or if they are unique to my little guys. One of those things that has been just driving me nuts these last few weeks, or so, is their apparent innate need to destroy things. Maybe there are mothers all over who are struggling with the same issue. Maybe I just have two destructive little boys who need to learn a lesson about taking care of things. Oh my goodness it drives me nuts!
It is not uncommon for us to be walking through the house or even through a store and boy number one will go out of his way to step on something on the floor. If boy number two is actually walking he will follow suit. There have been a number of toys broken by little hands and feet. There have been a number of things broken from being thrown or run over or whatever method they come up with at the time.
As I watch boy number one go out of his way to be destructive in some way shape or form and boy number two follow suit, I wince and wonder, "is this actually normal?"
