I mean, if people had more common sense and the rich dude didn't illegally quarantine on his yatch, inviting his dance cluster mum or grandmum, whatever it is; or if the mainland prostitute didn't stay in HK illegally and worked while asymptomatic, there wouldn't be a fourth wave. The Singapore Hong Kong bubble would have gone ahead, air crew would still be exempted from hotel quarantine.
The govt policies don't make sense, but it seems like people don't take it seriously enough to want to bring back a normal life. Why are people still meeting up for barbecues and hanging out in large groups indoors? Does this not defeat the 2 people in public rule and social distancing purpose? And why are schools and beaches shut but crowded new year flower markets going ahead?
