To be honest, I think a good amount of people could do well to worry about this, the amount of ignorance, arrogance and sheer stupidity I’ve heard recently is shocking.
When telling family about my anxiety over this I’ve been told by two separate people ‘Oh unless you eat bat soup you’ll be absolutely fine’ and also ‘I’m not worried at all, there’s a very low Chinese population here so it’s fine but I recommend you avoid Chinese takeaways if you’re worried as that’s the most likely way you’ll catch it’ 
If there was a bit of fear and panic in people they might stop being complete disgusting slobs and actually care about hygiene. This situation has highlighted to me so much about how vile people are, coughing in shops right in people’s faces, sneezing over objects and into the air. Not washing hands after the toilet or before eating. And several who have said they don’t care about this virus one bit and will happily travel and sit in crowded places without a care in the world.
The guy who threatened to leave quarantine is not a surprise to me actually because people are in general very selfish, rude and entitled.
Even though I HATE what my anxiety has done to me and my life, there are times when I’m weirdly grateful for it. I would rather be conscientious, over protective and vigilant to help protect my family and others who are vulnerable in society, than not give a shit like so many.
