I think Siri feels neglected by me. Last night, TVwas on and voice on TV said "Hey Siri". Siri asked how she could help and I had to tell her I wasnt talking to you. Siri said " Sorry". Today, driving, Apple CarPlay, Siri chimed in so I told her, I wasn't talking to her. Her response was "sigh".
Her revenge is to have auto-correct drive me crazy
