But you are implying that a large number of people refer to Father Christmas to make themselves appear 'upper class'- I'm not really sure why anyone would want to be associated with the green wellie brigade, citing your 'upper class' pal as evidence of the upper classes referring to him as Santa and it must be true as this very same individual is so very, very 'upper class' as she refers to Supper and has dedicated nurseries in her many residences because she is 'upper class' don't you know. She employs Mary Poppins and lives in Cherry Tree Lane- you seem quite desperate to prove your point!
No, I'm not

. You are mistaken and suggest you read my posts again.
But, if it's easier, I will reiterate for you.
The op suggested that Santa is lower class. The op brought up class in the first place. Another poster said it is common on MN for people to want to appear to be from a more upper class background and that they then insist they only say FC, supper, sitting room and so on.
I quoted that person and said there is an element of that. Because what the op said is actually a commonly held view in some places, it inevitably leads to those who are desperate to appear to come from an upper class background, to contrive to say whay they perceive to be the upper class thing. I was very careful to say then, repeatedly, that this does not apply to everyone who says FC. Another poster then said "don't get an inferiority complex about your accent" and another said "how awful to make fun of upper class english accents". I responded that it was intended in good fun and that my accent gets mocked all the time. I mock my own accent too.
My "vanity" which you accuse me of having because I am proud of my heritage, isn't such that I don't see the funny side of all the differences in regional accents. I love that we all sound different and I am lucky to have friends from all over the country and all over the world, from numerous social backgrounds and cultures. If any of them said that FC is the right one and Santa is dead common, as the op did, I would laugh myself silly. If they then took the hump, I'd probably laugh even more, inwardly perhaps, to be polite.
But, do read back over my posts. I think you Jace entirely misread them.
