"Yes!!" Oh! "Thank you! Um, I don't have a master though, just a Granny!"

A very nice master is the answer. "Granny's great though! We go on trains together, and go to see the market, and meet people who call me 'sweet potato'...and sometimes we find ones that are shaped like me!"

It's always a very good day, when they find a sweet potato shaped like a potato.
