As others have said, I hope that nothing bad has happened to anyone close to her. But the way she reacts is just bizarre. Surely if something had happened you would do what needed to be done (visit, or perhaps these days phone or provide other support due to the restrictions). You would inform people who needed to know, i.e work if you were due to be working that day, childcare, maybe a close friend. Then only afterwards and if you felt like it was something you wanted to share, you might update social media, or not, if you wanted to keep it private. The 'something bad has happened but I can't say what' just smacks of 2012 era 'DM me hun' Facebook statuses.
ETA we have 15 chairs in our house including all office chairs, sofa, dining table etc!
