I've told you before about thinking, it just makes your brain cell tired!

I know we've had this conversation before, but like you I would write in UK spelling as that's my education and heritage, but would use the appropriate colloquialisms which define the character.

It's interesting what sunny_d_lite says about Canadian spelling. Since being here I've got very confused sometimes, as it's a strange mixture of both English and American spelling - the 'z' is there, but so is the 'u'

Anyway, that's my tuppence worth, stick to what you feel is right for you - there's no need to apologise for it.
