I know a lady who is constantly saying “Really?” It isn’t used to say that something is truly that way, or to express surprise. It is used in an exasperated way. It is used as a way to express frustration. She does this several times a day, sometimes several times an hour.
The weird thing is that she is a grandmother. She is old enough not to say “Really?” all the time. It sounds so immature. It sounds that way because it is.
It isn’t the word that is the issue – it is the thought behind the word. She says “Really?” because she’s constantly upset that her version of reality doesn’t match up with actual reality. She’s constantly being unpleasantly surprised about how her version of real isn’t really real.
The trick is that she needs to adapt her reality to what reality actually is or she will constantly be upset.
