As you know about the idiom *read sth between the lines** it means:
- To infer or understand the real or hidden meaning behind the superficial appearance of something. "Lines" refers to lines of text on a printed page etc.
The question is that whether there is such an idiom in English or not:
- Say sth between the lines
Meaning: "while I have not forgotten and in order to prevet from missing sth I feel I should mention it right now"
Please have a look on my self made example:
I am describing my teacher's characteristics to someone who keen on knowing her, and say:
"She's truely smart! Emotional and over-sensitive individual who loves nature and most of the time during the break-time she reads some poems for us! Oh, between the lines she is a poet herself.
Does the bold part above work within my scenario?
