What is it called when you use one, very specific example/description which implicitly includes lots of other things, for example when you are describing a person?

I'm not talking about a metaphor like "she is my sun". What I refer to is more like, instead of describing qualities or feelings, you use one example that implies those qualities.

Example:
"She is the one who showed up at every football match" instead of describing "She always showed up and she was always there for you".

It's implied that she was not only fantastic because she watched every game, but because she always showed up, but you use an example instead of describing. (It's not the ultimate example but I couldn't come up with another right now.) The example says something more about the thing described than just the literal meaning.
