It was an ordinary summer day. People were milling on the main thoroughfare, bikes zig-zagging through traffic, cafés and pubs spilling onto the sidewalk, patrons sipping their way through a lazy Friday afternoon.

Just another family, managing the hectic jumble of kids' lessons, bills, our careers, endless streams of birthday parties, too little sleep and the occasional date night out. But it was all shattered with a single word: autism.
