people ask me why I am so pessimistic I reply "Simple. It saves time".
It is Friday afternoon. Almost beer o'clock. The weekend is looking good.
That seems pretty optimistic to me. Shouldn't you be assuming the pub will be shut, or that your other half will have too many jobs lined up?
Me, I bought barbecue charcoal, even though the forecast is rain. Life's too short to be pessismistic. Or is that too pessimistic an outlook?
