VERY Politically incorrect,

but none the less true for that.
When Ah waz a lad ... A "Silky" was a rather brown, turban clad gentleman, who arrived at our door regularly with a suitcase-full of "Silk" for sale, hence the name.

The only other foreigner(s) we encountered were Gino Gianetti in the Ice-cream/sweet shop and the blokes who came round regularly, in season, with bikes so loaded with Spanish(?) Onions that they were forced to walk and push them.

How things are changed.

Now, this is a Silky, we never set eyes on the other sort and the bike-loads of onions are extinct: and I rather fancy even our home village probably now has at least a "Chinese".
Off-hand I think you can dine, in Penrith, on Spanish, Chinese, Italian, various shades of Indian, a couple of Thai and I know there used to be a "Tex/Mex", not too sure about that now. I must do a census sometime on the resident nationalities.
