Unexpected 2nd dose

I was having a lazy morning. I started Tolstoy's "Anna Karenina" last night and I was laying on the sofa, reading. Suddenly, I get a text. I can book my 2nd dose of the COVID-19 vaccine. When? TODAY! J and I both managed to book our appointment right away. In less than half an hour we were out, on our way to the vaccination clinic. It's a bit over one hour and I'm alright. Last time I had a sore arm for about 48 hours, but not much else. Let's see how this one goes.
