Thank you for asking me to write something for your ACF London 65th universery event. Several years ago I was asked to give a talk in your centre. It was the first time I had been there. I enjoyed the welcoming atmosphere. I made several friends with whom l stayed in contact. I was at the time talking half the year in the USA .Coming back we were hit by the pandemic. I received regular information about the wonderful events you were putting on on Zoom. I hope that we will be able to attend the events soon in person again.
