2 seconds vs 2 minutes

E was arguing with me over the time he was given to watch his favourite TV programme, Ben 10.

Me " Ethan, if you read 2 books, then you can watch for 2 minutes"

E " 2 minutes only? so short!"

Me " It is not short, given that you will only need 1 minute to read each book."

E " No! It is not fair! I want to watch for 10 minutes"

Me " ok, we start with 2 minutes first, 1, 2. Let's read 2 books now " (literally counting, 1, 2)

E " No, that's 2 seconds! not 2 minutes! "

I was plesantly surprised that E has some idea of time! He would conveniently count it in his favour.
