I've had my 3 shots a little while already (double vaccinated since January & then boosted in April), but have honestly been a little disoriented in the difference in COVID protocols since coming home - so sadly am unsure how long I can stay strict about it...
In HK, you still need to mask indoors - they lifted the requirements for people exercising, but I still keep mine on at all times except for outdoor swimming. You now cannot eat at restaurants etc without being 'triple' vaccinated (2 shots + booster) so whilst I do take advantage of that now, we've been trying to minimise it by eating it/ getting delivery as much as possible. That said, social distancing is pretty much impossible there due to the population density, so people only half adhere to the distance markers in queues (e.g. at the post office). The rest of the time it's just as crowded as ever, even in swimming pools etc (they had crowd control before due to COVID, but now not so much)...
On the other hand, the UK seems to be more obsessed with social distancing rather than mask wearing, but people seem to be 'giving up' the distancing whilst socialising (e.g. at weddings). It's made me a little nervous to be honest, since I've still been wearing my mask out of the house since getting here, but even on the plane many folks weren't wearing theirs (despite the airline supposedly requiring masks when not eating...) My mother is already pressuring me to attend some weddings where I *know* most either won't be masking, or will want to be hugging & taking photos with me unmasked. I've already told her I won't attend unless I can continue wearing my mask, & she's agreed, but my mother has also been known for yanking my father's mask off his face because she 'couldn't hear him', so I don't have high hopes she'll actually 'allow' me to when the time comes...
TL;DR: I'll do my best to stick to my COVID prevention (despite having had 3 shots) but at this point I've resigned myself to likely catching COVID during this trip. I just hope it's sooner rather than later, since I won't be able to re-enter HK without a negative PCR test (& even then, I'll have to quarantine for a week in a hotel). Part of me feels this is why we keep getting spikes then dips in the COVID rates - people are impatient about getting back to 'normal', but don't realise how some of their behaviours may ironically be contributing to the delay of said 'normal'...
Anyway I'll get off my soapbox now, just a bit miffed that others won't let me be cautious in peace - they'll likely be my downfall, lol...
