A person i knew once told of being on the commode when the Sylmar quake hit in 1971. Said they were thrown off the ‘throne’ and the contents came out. Said the experience was not at all funny.
Heard that story.
(Two houses went down in my parent's neighborhood & their elm tree "grew" a foot.)
Now I can empathize; watching, from the inside, while a two pane shower door rattles and leaps around is a real motivator.
The neighbor kids will probably be reminding me of how I look in a pink chenille bathrobe until I move or they go to college.
