What does it mean when someone says, "It's nothing to write home about"?
Answer
The expression "It's nothing to write home about" is a roundabout way of saying that something is not of high quality. Here is an example of how it is typically used:
Tom: Where did you eat last night?
Jessica: We tried the new Chinese restaurant around the corner from the movie theater.
Tom: Really? I've been thinking about trying that place. How was it?
Jessica: Nothing to write home about. I wouldn't bother going there.
Tom: Too bad. We really need a good restaurant near the theater.
When Jessica says, "Nothing to write home about," she means that the new restaurant isn't particularly good, or at least that it's no better than average.
The related expression, "Something to write home about" means the opposite, that the thing you are talking about is quite special. However, this expression is rarely used.
