For my far-flung readers, some context: the UK is in a second full lockdown. Unlike Lockdown-Lite in November, schools are closed, “non-essential” shops are closed. Ditto pubs and restaurants. Stay-at-home orders are in place. No travel, no non-essential journeys anywhere. An hour of outdoor exercise once a day is fine, but no mixing with other households. The result is that the majority of families are home together pretty much without interruption. Adults who are able are working from home. Children are remote learning.
