I got up last Saturday morning and decided I wanted to go to the other side of the planet.  On Sunday I got on a plane.  I kept expecting something or someone to stop me, even a stranger in the airport to shake me and say “Don’t be crazy!”.  It never happened.  I expected the check-in staff to laugh and say “Ha ha, you want a seat?  But you only booked it yesterday, you’ll have to sit on the floor the whole way!”.  But no,  they even gave me an aisle seat when I requested it.  Spontaneity is not a crime.  Who knew?
