Taking
something at
face value means to not look any deeper into what is being said. If the listener tries to read into it, the
wrong conclusion will be reached.
No ulterior motive. Just read/hear what is presented and do not read into it.
Take this at
face value, but you look really hot today. Where did you get that shirt? (If the listener didn't take it at
face value, he/she might wonder if the speaker is interested, romantically or otherwise)
Take this at
face value, but you had mentioned the cost of getting a nose job yesterday and how much you wanted one. I saw the prices. They'
re really not as bad as you thought. (If the
face value clause were not said, the listener might be offended. It could be construed the speaker is implying the listener should get a nose job because it looks bad or whatever)
