Maybe, maybe not

Right now the 3 weather forecasts on my home page say it will be mostly sunny today.  From what I can see out the window from here, it looks partly cloudy.

Is this a case of you say "The glass is half full" and I say "The glass is half empty"? 

Or is this a case of "Open the blinds so you can see what you're saying?"

We may never know.  I don't think I care enough to get off my duff and walk that far.

You may say "The glass is half full", but I say, "Who's been drinking my whiskey?"
