Many years ago when cigarette smoking was a common activity I held out my pack to a friend so he could take one. He took two. One he lit and the other he put behind his ear.
"One for Ron." he says.
"Ron?" I queried.
"Yes," says he. "For later on.".
I was reminded of that as I watched a Grey Squirrel helping itself to some peanuts I had place in a dish on top of the Hedgehog House.
Very much an example of 'One for Ron" as it ate some and buried many in the grass to, hopefully, find again 'later on'. (No sound from this camera)
