Left overs always nice to enjoy next day, fish has become more expensive, trout and salmon most probably two that come to mind are never cheap.

Good Morning Joan, I am rather cautious with left over fish, other leftovers I'll leave for days, nibbling on it until it's gone, but no, you know the old saying "House guests are like fish, after 3 days they begin to stink and should be thrown out"
I believe this is true, with some notable exceptions ha ha ha

"Waste not, Want not..." eat and enjoy.

House guests I agree 😄 depends who they are!
