Dogs sniff out Covid

‘Where are we supposed to go to stuff our faces?’
‘It’s not wearing a mask!’
‘Why are we here?’
‘We’re going on somewhere!’
‘It could be worse, you could be Gavin Williamson.’
‘I haven’t seen you on Zoom lately.’
‘Fourteen weeks of lockdown and I still haven’t read Ulysses.’
‘They’ll be stuck in her in-tray for 14 days.’
‘Then lockdown happened and I started getting interested in them.’
