Deffo, it's the weather.
One slight correction barrygeo.
We drink, play music, write poetry etc AND go stark raving mad. Life is much more interesting that way. I am proud of my insanity - and, all my friends are quite daft. I am only on nodding aquaintance with sane people - and I feel so sad for them. It must be dreadful to view the world without the colour and variety which madness bestows.

The weather. No doubt about it.
