"Are you sitting comfortably darling? I'm sorry - what did you say? Mmmmmphh mmmmmmmph? I'll take that as a yes shall I? Don't worry, we'll just make it thirty minutes for today's riding lesson."
OK - the illustration is perhaps rather too severe to emulate in real life. Fantasy artwork and reality are often somewhat removed.

The artist is unknown.
