Peter changed into his pyjamas, brushed his teeth, shaved and settled in front of his computer for the Friday night whole-family video call that Mary had started when the lockdown began, ‘to keep their collective spirits up’. She lived two streets away with her husband and twin daughters. David dialled in from Napa Valley. Between Annie’s drawings, Katie’s handstands and David’s virtual tours of his vineyard, they didn’t get much talking done, which suited Peter just fine.

The only good thing about these calls was that he didn’t have to make eye contact. If he pasted a benign smile on his face and stared somewhere in the proximity of the camera, he could get through the whole call analysing his own receding hair line. It helped that Olivia preferred to dial in from her own phone from her own room.
