"I don't think I quite called you a liar, Karolina" Well, that's what it looked like to me. "You aren't what you say you are" is what I took flattop to be saying. Which is fair enough in a way, because there are jokers around, and that's the kind of game jokers play. But it's not a friendly way to greet a stranger.
And welcome to the Mudcat, Karolina. We're pretty friendly most of the time. And the more globally diverse we get the better.
