sometime BC (Before Covid) I found my old cheque book, the only butt in it dated 2018) so I started using it as a notebook beside my phone.

During lockdown muso friends started lockdown youtube concerts to get some income. As I still had a few cheques in the book, I sent 3, one for them & $20 each to their kids. Father said the girls were very pleased to have some money of their own to spend! Perhaps he had to explain what cheques were.

Speaking of explaining, earlier this century the "Overheard" column in the local paper reported a conversation between 2 young women on the train - "I've just finished jury duty & they sent me this nice bookmark."
"That's not a bookmark, it's a cheque & if you take it to your bank they will give you money for it" (here jurors get a daily payment for their time)

The "Overheard" column was very entertaining.
