Nut and bolt

A miserable grey wet day all day today.
First half a day in the hospital for a CT scan for my wife and after that at the warm stove.
But tonight we had still to make a picture for the blip. But what? Then you run through the house, to above nothing, in the basement and that is always a place where you can find something. Similarly this nut and bolt in a piece of wood. The piece of wood is a leg of a table and with the nut and bolt set the leg stuck to the table top.
