Oh, this old thing?
Twice in recent weeks, I've given someone a compliment about one thing and had them assume that the compliment made was for something else.
They go on at length about the thing that they wanted to be complimented on. The thing that they are especially proud of that surely must be noticed by all the world.
In these cases, far be it from me to correct them and go on at length about what to them is merely an element of the backdrop.
