Going with the flow

Most everyone I know has been using these regularly but I'd not even seen a lateral flow test before.  Therefore I was very pleased to pick these up from our village chemist (where there are some new faces as Deepa is taking a break).  

This means that the next time I see my Dad, or anyone else, I can be more certain that I'm not an asymptomatic carrier of Covid-19.  Phew.
