Tommy Wallach wrote:My take on his one is that it's not about an idiom with "conclude," it's an idiom with "satisfaction."

Basically, you say: "This is to my satisfaction."

So you also have to say: "This has concluded to my satisfaction."

If we were just using "conclude," we could say lots of things:

"The movie concludes by wrapping all the loose ends."
"The movie concludes with a big dance number."
"The movie concludes in a gripping one-on-one battle between Ralph Macchio and the mean kid from Cobra Kai."

Hope that helps!
