Person A: The weather is beautiful today, clear skies, low humidity and 80 degrees.
Pessimist A: Yes, but it rained ten days ago.
Pessimist B: Yes, but it rained a year ago on this day.
Pessimist C: Yes, but it will rain sometime in the future, just wait.
Pessimist D: Yes, but it's raining right now in Nebraska and Nepal right now, so it's not beautiful there at all.
Pessimist E: Yes, but the government manipulates the temperature and humidity readings, so if the temperature and humidity were re-calculated according to Shadow Stats, it would really be ten degrees warmer (or colder), and more (or less humid), so you can't trust government data, and the weather is actually horrible now, not beautiful.
Pessimist F: Yes, but if we don't get rain soon, we might have a drought. (ht/arbitrage 789)
