Castle in the air

I wondered why this was the only picture I took today until I thought back over my very demanding day. Despite that, I managed to leave work before the chemist closed so I could collect the first pack of lateral flow tests I've been able to get for a month. I, like many other people, have not been able to check whether I am a risk to others when I go out. I reckon there's a fair chance that has compounded the rapid spread of Omicron.
