Very mild; dismal windy morning but clearing up during the afternoon. To Wimbledon to do shopping. On my return found Mr & Mrs Mc'Ainsh with little Jeanette to tea. Played my violin while Mr. Mc'Ainsh accompanied me on the piano; he is a good player. Flew my 37 ins model on the Common in evening with excellent results. Mr. & Mrs Jones were there, he with a new red model resembling a Spitfire which did very well, having an unusually slow glide.
