Well, not really misspelt it, just using another variation of it such as Elisabeth/Elizabeth or Susanna/Susannah, Margo/Margot, Mae/May?
Not really, it can be fairly easily done if it's an unusual name. Can be tiresome to keep correcting people though, so I take the liberty of spelling it for them as soon as I say it.
People misspell and mispronounce it daily. If I got annoyed I would always be!
Not really, would be something pretty stupid to get annoyed about.
Yes, people always spell my name with a C instead of a K, so I always have to say Katherine with a K
But is it a genuine error?
No, it would take a mentally deficient person to spell my name wrong so I obviously wouldn't be annoyed by it.
No. My name's Sofia and people tend to spell it as Sophia. I'm called Sophie all the time.
