When we were in CP a few weekends back watching Dave run a race, Graham decided to start waving. And boy did he go for it - he waved at every runner that passed for a full hour! A few people on bikes actually waved back and he was amazed. And a little terrified. Any response would promptly cause his eyes to widen and his bum to plop down in the grass. But he'd recover quickly and be back to furiously waving in no time.
