A Silly Way To Spend Hours

N o, I have not turned to drink, this is T's latest jigsaw completed.  He finished it last night, so I told  asked him not to break it up before I had taken a photo this morning.  If you look closely you can see how small the individual pieces are, I have taken some out and placed on the side to give you an idea.  If you look even closer you can see where those pieces fit.
I admire T's patience in doing these jigsaws, but it seems a very silly waste of time to me.  He spends hours doing these difficult puzzles then takes them apart and puts them back in the box.
