E-bay message, received today: "Shop your faves". I don't have any "faves", although I might have some favourites. Or I might not.
Something being described as "Unmissable". No it's not. I can usually miss it quite easily, thank you, by accident or design.
The same with "must-haves", (Vista Print today), there is no requirement for me to buy them, whatever they are. More likely they will go into my "must-not-have" list after that description.
Why there is this constant desire to ruin and abuse a perfectly good language, I will never know.
