If anyone gives you grief because the small pieces of cloth that cover your feet are slightly different colours you should feel completely free to tell them that they should maybe reexamine their priorities in life.

So many things, so much more important then mismatched socks for a day..

That said l, glad you caught it. Mismatched by choice is one thing, mismatched by error might leave you unprepared to deal with the social fallout 😃
