@oldtimer, perhaps it doesn't translate correctly, but sir can have any number of connotations in English, sometimes even just for fun, as in "Yes, sir!" :D Regarding the squirrel comment, I think she's just kidding with you about your profile picture. You do realize it's a picture of a squirrel, and your profile says "Don't touch my acorn"! (ie. what squirrels eat) lol

Sounds like all just a simple language misunderstanding to me... :)
