I have avoided facebook until lock down started and unwillingly downloaded it so could find out about local services and supplies etc. It has been very useful for that. I also joined a very lovely knitting group. My privacy settings on highest level. I only have real life friends and never post anything personal such as photos. I'm not very trusting of FB as a company.

To think that London, or anywhere else for that matter, does not belong to any one demographic
