I'm the laughing stock of my family. I'm prancing around, holding my watch up and saying "Hey Siri!", "HEY! SIRI!!", "HEY SIRI!!!!!!", and she almost never answers. Maybe, 1 out of 10 times. It worked much better the first day, but it seems to slowly getting worse. Then sometimes she hears me, but she never answers. Sigh. It would be such a neat feature if it worked.
