When things fall apart

I am a creature of habit to the point of compulsion. I like things the way I like them, and I like them just so.
Still, when faced with the so-called chaos of the system breaking down, such as the TTC this morning, I always surprise myself with how little an upset of events like this affects me. You're never going to find me freaking out, pushing and shouting. You probably won't even find me grumbling. I'll just be chilling, listening to my iPod, waiting for the shuttle, finding an alternate route, going for a stroll instead.
I think back to my international travels, and how I met any "crisis" with flexibility and optimism (with two notable exceptions, the first being our Hotel California-esque inability to leave the Pink Palace in Corfu, and the second, upon being told that we might not be getting on the plane for our honeymoon, where I threatened tears). I would generally say that I'm highly adaptable.
I guess I'm wondering why I try so hard to control the little stuff, when I clearly understand that I have no say in the big picture. Maybe that is why.
