I presume the relationship between Little Red Riding Hood and the person she’s visiting is a Granny knot?
That is the knot I always used and was told it was a half Windsor many years ago, I still havre a couple of ties with the knot in place in case of emergency
I agree, that's a half Windsor. A Windsor does both sides and it's twice as thick. My Dad taught me that one, and I still wear the half Windsor - with most ties. A full Windsor looks like you're trying to make some statement! I believe, without checking it was the old Duke of Windsor who advocated the Windsor as thick knots were the fashion.
