During the temple ceremonies, patrons are asked at various points of the ceremony to consent to a covenant, or demonstrate certain actions.  Once completed, the dialogue says “That will do.”  It always reminds me of a scene in the children’s movie “Babe” where the farmer tells Babe, “That’ll do.”creepy animated GIF

Maybe I’m getting too hung up on different phrases, but I’ve always wondered why another phrase, such as “Thank you”, or some other acknowledgment might be used.  What are your suggestions?
