Sorry, I'm obviously in a generally pissy mood.
I've had emails from four different people already this morning misspelling my bloody name and it irks. Probably irrational, but my name is NOT common-variant-number-one (let's say Jane). It's common-variant-number-bloody-two (Jayne). I have an extra letter, but it's still a very, very common spelling! Miss it out and it's not me.
Misspell my surname and I couldn't give two hoots, it's forrin and hard to remember - I get that, it's fine. Misspell my first name and I feel 'not seen', but that it would be far too petty to raise with you. I feel especially narked if I've paid a lot of attention to spelling your name.
I am totally, irrationally U on this but by god, it rankles!
