I wasn't offended in the least, my friend! I was pulling your leg re the invite and it being for Nick only, hence the emoticon at the end. If there's one thing I never do, is get offended (hell, the damn world is over-sensitive enough as it is, being ever so boringly "PC"!)
Having said that, I never intend to offend others, but my sense of humour gets taken up the wrong way sometimes. Especially in text, since no-one can see the constant twinkling in my eyes...
