Visiting the parents

I haven't been home for six months. Maybe that's why my Dad didn't recognise me when he picked me up from the airport. I spotted him and walked straight towards him. He showed no reaction until I was standing 6 inches from his nose. I'm not so sure why he was so surprised to see me there, I thought that was why he was standing in the airport to start with.

When I got home I was offered tea and biscuits. "Would you like shortbread?" I was asked. "Yes, please" I answered, "that would be lovely."
"Would you like a digestive biscuit?"
"No thanks, shortbread would be great."
"Would you like a banana?"
"No thanks, shortbread would be great."
Then when I am eating the shortbread "would you like a banana?".........

Sometimes I have been told I am a patient person, maybe I have my parents to thank for that. I have been training for many years....
