I was called up last month for two weeks to a court which meant a train, bus and tube ride. I have been careful so was very concerned because I knew I would not go. In the end I completed the form saying I am over 70, live miles away, have been very careful and can’t do it. I also said I had done jury service years ago. I got a letter back excusing me from service.
Strange that most of my friends etc have never done jury service and I was being asked to it it a second time, in the midst of a pandemic. I don’t think so!
Write to them Linnana, I was worrying unnecessarily, they won’t make you.
Good luck.
