Ha, that's good advice at any time of the season tbqh!
But I don't mean to panic anyone, but there will be people dozens if not hundreds of people who catch it tonight who in the best case scenario won't be seeing family on Christmas day. My partner's cousin in London has got it, and she's fine, but there's a lot of it about at the moment.
I'm still coming tonight, I'm thrice jabbed and have already had it, but anyone who wants to still come tonight but be careful should get in early and avoid crowded indoor spaces.
