Holy Fukking Sht! I'm sitting here, surfing Pelican, waiting for the family to come home, when all of a sudden a ridiculously loud glass/bell like clang sounds out from the kitchen/dining room. I walked over to find this:
The glass cover to the dining room ceiling light spontaneously fell off, plunged to the dining room table below, and smashed the glass top. There's a little metal knob/finial on the tip of the glass dome, apparently.
That was 10 minutes ago, and I still hear the glass cracking like Rice Krispies.
