I grew up (I’m mid-50s) calling it by its full name rather than MSF; whenever its mentioned on the BBC it gets it full name; people in conversation here call it its full name. It too have travelled and lived in different parts of the world for my job with a charity - Middle East, Africa mainly, as well as South East…

Nope. It’s MSF in the UK. Always has been.

But gay and closeted so unless you are a bloke you’re wasting your time.
