I confess in the moment when you weren't even using a phone, I probably wouldn't have got it either. "What do you mean? I didn't throw my phone at you..."

I lived for a while with some very Öko people, and had a sort-of-aunt who was easily panicked about her pacemaker, that's where I encountered this in the wild! But, ages ago. I think even that sort-of-aunt now has a mobile phone. *g*
