I’ve enjoyed reading your thread this year, sharing all the ups and downs of the early months, so thank you for all that - and, Brendan, your mention of newcomers has spurred me to register!
I struggled a bit today. It took me a long time to catch what ‘caught’ meant in 18A! And I still can’t parse 17D - I thought the solution was used only verbally, whereas ‘drivel’ is a noun. Besides, i’d have thought dribble was closer to the definition. Or am I missing something?
My final puzzle was 12A. I read it rather as ‘confused when left *in*’. It’s attached when left out!
