'So you are not happy with your dark chestnut pony? Well, I can offer you an exchange, as I would not want one of my horses where it was not desired. However, this is not a decision to take lightly, so I will give you a moment to think about this.

'If you are really sure you wish to exchange your dark chestnut pony, speak to me again, and I will give you a receipt in return. You can then exchange the receipt for a dark chestnut horse or pony.'
