I’m not going to name names, but it seems this needs spelling out.
Ladies, DO NOT pull a gentleman’s tie. It’s not funny. It’s just annoying.
A tie is a highly-tuned precision garment. Sometimes it’s a great deal of effort to get it looking just right. Sometimes it’s even a great deal of effort to get it looking even half-decent. You mess with it and it’ll be uncomfortable and look awkward until it’s pulled off and completely re-tied.
So please don’t.
