I'm nervous about dd going back, but that's partially that we're at a very low area-Durham is approximately 10x the numbers that we are!
But she needs to get back, or I think she'll lose her nerve and not want to go back ever.
She was just really settling in when she came home, and although she had a couple of sad days mid summer term when she realised that they weren't going back that year, she really is a home bod and would prefer to stay at home.
She did suggest she could stay at home as lectures are online, and I've said she needs to go back as the longer she stays off the harder it will be. She does seem a bit depressed to me though she won't admit it.
She's only in a house of 3 people, and they're all doing maths, so the risk should be fairly low between them. I've suggested she takes a huge bag of rice and a number of pasta sauces back so if they do get put in lockdown they can survive a couple of weeks of not going out!
I am glad though that they're relatively late back, because it does mean we may be able to see if any effect is coming through and make decisions accordingly.
