"What's the matter, Ponder?"
"I'm pondering life."
"You do know that your name isn't program? You were named after ..."
"I know, Ponder Stibbons, a Discworld wizard. Because all I am is a wizard who's a nerd that runs a computer with ants in it and wears glasses."
"Yeah, well. I loved the name. Greebo was already taken and ..."
"For a cat that is as laid back as they come while the real Greebo is the terror of small animals and everyone else beside Nanny Ogg."
"But ..."
"Don't disturb me."
"Any thoughts on life yet?"
"I like the odd sunbeam."
"That's it?"
"You interrupted my pondering."
"I'm sorry."
"Yeah, right."
"No, really, I ..."
"Go away."
Dismissed by a cat. I hope they'll put that on my headstone one day.
