Up or down

I have taken to riding on the top of the bus.  I used to ride on the lower level on the way to the office and on the top on the way back home.  I have no idea why...it was almost like I gave myself a little reward for a day of hard work.  I then realized the other day that the upper deck of the bus is much emptier in the mornings so I have started riding on the upper deck both ways. 

Today I started wondering what makes people decide to go up or down.  For kids I think it is an easy question, most of them want to go up and most want to sit in the front.  It is fun to be above everything else and to see where the bus is headed.  Adults seem to be different though - some like heading up and others are content staying down...even if the lower level is completely full. 

To me I think it is like choosing the best seat in the car when you are a kid...especially if you had siblings.  Of course the front seat is the absolute best seat to have.  However, if you were lucky like my brothers and I were we had a station wagon so the absolute prime seat was the 'way back' of the car.  That would leave two to share the backseat and one to have the entire 'way back' all to themselves.  It was like our own little kingdom that moved.  Although I don't seem to recall winning the 'way back' too many times.  Maybe that is why I have now decided to ride upstairs all of the time...and yes, I am like the little kids and try and get the very front seat.
