No has recently discovered the joy of waving. If she sees herself in the mirror, if anyone comes into view, if she drops a piece of fruit on the ground, if anyone says hello/bye/hoi/gruezi/tschuss/adieu/ciao (etc) within earshot, she waves like a tiny maniac. This arvo on the train she apparently wanted to engage a few strangers and it was so adorable to see them fall victim to her charms. Even the particularly childproof-looking man next to us who had both a book and ipod to absorb all his attention couldn't stand more than a few minutes of No's charm offensive before he was waving back and pulling silly faces at her.
And they say the Swiss are a cranky bunch of grim-faced meanies.
