So very sorry to read all the surreal and sad ones.
I remember the last couple of days just before the decision to lock down, the last time I commuted. It was the first time I saw the disposable PPE style masks for sale in a pharmacy, a handwritten sign on the door saying they had them - one box on the counter, of about 50 and for sale singly. Waiting for the train on the platform - this was the afternoon so not very crowded - I remember counting people and weighing up my chances as to how full or empty the carriage would be as to whether I'd get on or wait.
Other memories include trying to make the best of the beautiful early weather in the garden, clearing out the shed thoroughly etc, but still feeling trapped in.
