During the Covid lockdown, the BBC produced an explanatory video about the 2m social distancing rule. It featured a reporter talking to members of the public, while holding a broom out in front of her to illustrate the space required. I was reminded of my tiny broom I used in my dolls' house and it seemed an obvious parallel to give it to this little doll I used to play with. Covid was perfectly represented by an old rusty Corona beer lid that my son found while we were beachcombing.
