Mummy. In most people’s houses, they are allowed to eat on their couches.
Really? Who are these people?
I have not met them yet.
Then how do you know?
It just seems likely that other people would eat on their couches.
Oh. Are you saying the probability that we are the exception is strong?
Yes. That is probably the case.
Are you possibly trying to convince me to let you eat on the couch?
Yes I am. I think it has not worked.
Correct!
