Lovely story MZ - I could picture it all taking place as I read it. 
Thank you all for your comments, they are appreciated.
It was, of course, based around my own experiences, both past and in the present... Once I was the Student, now I am the Master (Only a Master of evil MZ!) and guide others, but I am still humble enough to learn from the horse when it feels the need to teach.
You can blame the story on the fact that, last week we ran a Saturday Service on the railway, so I had to sit in the office for eight hours a day with nothing to do.
