Radiators & Drains

Today I did an assembly on radiators and drains - where radiators are people who are optimistic and drains are the pessimists. It made me think about the circle of friends around me and more importantly whether I was a glass half full or half empty type of person.
Having considered myself as an optimist mostly, I've been surprised at how pessimistic I've been today!
So... It's time to rebalance things methinks!
