They might assume you are less than super-smart.
Say, for instance, you enjoy quoting lines from the 2000 Christopher Guest movie “Best in Show.”
And let's further suppose that a co-worker or casual acquaintance overhears you telling someone on the phone, “If you get hungry, eat something.”
A person overhearing that might well wonder if you or the individual to whom you were speaking inhabit a land of absurd obviousness.
When, in fact, it's just your grand sense of humor. Or at least Christopher Guest's.
