French leave or holiday comes from the fact that we distrust our neighbours so intently and in the past anything unseemly was said to have been derived from our closest neighbours so we get French Kissing - because it was supposedly debauched, french letters - unseemly because no one talks about sex and when someone swears they still may say - pardon my French. It just stems from a dislike for our neighbours and many other countries have their own versions. I'm sure the fountain of knowledge that is QM will be able to give a much more detailed explanation.............
Nope...what you've said sounds pretty good to me, Derby. I might just add that - whilst we speak of 'French leave' - they speak of 'English leave'. The dislike is a two-way process, in other words.
