Last week’s good vs. bad news
The good news last week? Well, I went to Chelyabinsk – that’s the first piece of good news. Okay. I need to keep score here. The referee blows the whistle. Game on. 1:0…

I won’t waste time explaining; I’ll just quote our report from the frontline: “One more major lawsuit is added to our list of victories! Case closed – not a cent to pay out!”
