My world shook last night.
The ground vibrated. The lamps in the balcony and the living room swayed. Not a problem with my head, I realised.
Ah Ma was telling us that if that goes on, we had better go down.
Which led me to wonder: Shouldn't we stay right where we were - on the 19th floor - or go even higher so that if the building did actually collapse, we would be under just 1 storey of rubble and not all 20 storeys of it?
