There's no requirement to test but I view it as a social responsibility. I sat with my son next to me for six hours on Tuesday, he had a very bad cough, we had a 30 minute cuddle watching TV. We spent 90 minutes in the car together. He's positive so there's a high possibility I will be.
Tonight I was due to meet a friend and work side by side on his laptop, Friday in a quiz team, Saturday manning the bar, Saturday or Sunday Club Ride and sat in a cafe, Sunday evening theatre trip, Monday night football, Tuesday is granddaughter day. All of this with family and friends, four of whom are clinically vulnerable with suppressed immune systems.
For me, and this is very much a personal view, I think it would be highly irresponsible not to test and also to make a decision about each individual activity.
Tests are £2.50 each. I suspect I'm very much in the minority.
