You can't “save Christmas” by going into yet another crazy senseless lockdown.
You enjoy Christmas as usual with your friends and family.

I’m not sure if you’re familiar with the tracking that the UK has in place. If someone tests positive, their ‘close contacts’ are notified to quarantine by NHS via cellphone. Once notified you cannot travel and you may be checked up on.

With Christmas so near, and knowing Omi may evade immunity, Brits are choosing to lay low a few days and not risk that NHS phonecall.

Tomorrow they can travel home to see Mum and have their holiday fun. If they get infected or a ‘close contact’ call afterwards, well, it’s better than missing Christmas, isn’t it?
