I'm editing someone else's work, and they have a tendency to throw the word "would" in when it's not all that necessary.
"I would think you'd have done the opposite." --> I thought you'd do the opposite.
"I thought it would have made sense." --> I thought it made sense.
While the first sentences aren't wholly wrong, in an effort to make things more concise, I'd like to suggest the changes, but I don't have a strong grammatical argument for WHY, other than "it's shorter and better sounding." Can anyone help me voice why the changes are better?
