Death by Google Calendar

"Maybe I missed something, but why does one person being out of the house mean the house is empty? What about partners, housemates etc?"
House mates are clearly possible, but her calendar never mentions any partner like it would if she was married or living with a partner.
Maybe you missed the bit where the author did a cursory glance through and saw no mention of another half, or of kids. I guess you could extend that to lack of info on housemates, etc, and take it from there?
