Guessing game

The following conversation happened in our car this afternoon:

Em:"I went shopping and brought some flannels, guess what colour they were"
Jo: "Red"
Em:"No, have another guess"
Jo:"Yellow"
Em:"No, have another guess"
Jo:"Blue"
Em:"Yes, well done!"
Jo:"Guess colour again"
Em:"I went shopping and brought some flannels, guess what colour they were"
Jo: "Red"
Em:"No, have another guess"
Jo:"Yellow"
Em:"No, have another guess"
Jo:"Blue"
Em:"Yes, well done!"
Jo:"Guess colour again"
Em:"I went shopping and brought some flannels, guess what colour they were"
Jo:"Blue"
Em:"Yes, well done!"
Em:"DO you want to guess again"
Jo:"No"

It amused me
