Letter to the sprats

Dear Sprats,
I had a fine day yesterday visiting you all, it was good to see you in your respective nests.
However I feel the need to make this announcement:
The next time you come up to visit me in my nest, I shall be delighted to see you, take walks with you and talk with you on the many cabbages and kings that interest us both.  If on this visit you leave some of your very important belongings in my care, they aren't going to be driven down to your place.  You can retrieve them in your own time and with your own vehicle.  I am not doing this again.  I am too tired and the weather is too hot.
Love,
Ma.
