Some years ago a met a men of Russian descent whose grandparents had fled Russia during the revolution. They were wealthy landowners, related to the Tzar and knew that they were running out of options. When they arrived at the border they were dressed as peasants but the guards were suspicious and asked to see their hands. Fortunately both of them had been working in their vineyards and had "peasant" hands. The guards let them through and they lived to tell the tale.
Last night I was reminded of this. We went to a friend's house near here and met many new people. As occasionally happens someone asked me what I do and I told her I was an upholsterer. Straight away an elderly gentleman who was also talking to us, asked to see my hands. He had a good look, both hands and both sides, and then said words to the effect of "good".
Yes I was curious! This gentleman, I discovered, was part of the family who have run Toiles de Mayenne for several generations. He has now retired and his sons now run the company. His wife was also part of the business helping to choose colours and designs. It was fascinating talking to them although I still don't know if my hands passed the test.
