@cx that's interesting. Mine unfriended everyone and changed into a completely different person overnight. From what I gather the reason behind it was to 'protect themselves'. I stood there flabbergasted but I didn't day anything, I thought to myself from what?
Keep in mind this person knew me a better part of a decade and we both shared updates about daily life without any issue. A close as a family friend even acting. Still hasn't fully recovered and that's been two years now.
