My thought for the moment:
When life gives you lemons: squirt them in someone else's eyes.
Why? Because A.) then you won't be miserable by yourself and B.) it will bring some humor into your miserable situation....I know it's a rather sadistic and bitter thought...but that just happens to fit my current mood.
So if you just talked to me and your eyes are burning I apologize...I might have just squirted you with some lemon juice.
