Random observation #1

The leaves outside my office window are falling up today. That means either:

1. The earth's polarity has reversed and they're being sucked out to space;

2. Christopher Columbus was wrong and the earth, indeed, is flat - and we've gone from the top side to the bottom side; or

3. We're about to receive a visit from a big honking storm.

On a related side note, there aren't any trees in the courtyard below, so where are the leaves coming from?
