Back of the bus

Jeff just called to tell me that his plane just arrived back in Houston.

Me: 'How was your flight?'

Jeff: 'Kind of bumpy, but I ate and then fell asleep.'

Me: 'Is it true that the back of the plane feels more turbulence than the front of the plane?'

Jeff: 'Well you know when it is cool to sit in the back of the bus when you are in elementary school? you bounce around on the seats and it's really fun?'

Me: 'Yeah!'

Jeff: 'Well when you are an adult and you are 30,000 feet up in the air, it's not so cool anymore.'
