(Dan) Play your sax, man. It's not an instrument I can play but picking up the 'bone and giving it a whirl is most satisfying especially if you find something to play along with (stuff on YouTube usually). (Stevie) I've occasionally forgotten to plug in and muttered to myself "this doesn't sound right" followed by "plug it in, twatface". The neighbours are upstairs, sleeping the sleep of the just, and are not disturbed, so I have ascertained.
[pen] I learned the front crawl. Actually, I had a series of lessons before lockdown, and then the pool closed, but since it opened a couple of months ago I've been practising. I can just about do a 25 metre length without stopping. The skill of breathing air and not water is the difficult part.
