You are most welcome!
This "guys" reminded me of one experience I had in a British Message Board, I came frolicky and wedged the "guys" word in the conversation. The Forum certainly has old timers, in the sense that the age bracket is in average higher than mine, whatever...but the fact is, the nice ladies of the message board let me know in no incertain terms that they wouldn´t like to be called guys.
Wether it comes from the British care with purity of language, or that I was perceived as behaving as an slangy teen don´t know!
Anyway, the moral of the story to me was, I had to heed the audience...if I was addressing someone older or his language mores!
As for me, no problem you can come and say "guys" to us, LOL (others will lung at my throat for this LOL, ha ha).
