Later I started Lecture 2 on General Relativity by acclaimed Stanford physicist Leonard Susskind. Once of the best teachers in the world talking about one of the most tedious subjects (covariant and contravariant tensors, and transformations of the metric tensor): I literally fell asleep after 25 minutes.
And then this video. The setting is Marissal Road, Henbury, Bristol. Alex and Adrian, together with my sister Elaine, are visiting my mother (this was some years ago). I am my usual bumptious, overbearing self with a camera; my mother (with her robot cat, Cindy) is inveigled into the role of camera-person.
Despite everything, it's quite amusing.
