I'm translating a short story from English and I'd like to know how the modern Americans would decipher the following element of body language:
"His mother sometimes looked our way as she came and went from the house. She didn't reveal anything that we were mature enough to read—only kept on, often with a hand pressed to the small of her back".
It's from a short story by a comtemporary American writer, I won't describe the context yet. I'd like to know what this description can tell about her hidden feelings (the caracter is an adult American woman living on Long Island).
I've Googled it and I found only lots of "his hand pressed to the small of her back" in erotic context.
Thanks, everybody! Most commenters have perceived it as "backpain" or "pregnancy".
A bit more context: The woman is a minor character. Little is said about her except this scene where she is looking at the students of a school near her house (it's possible she bears a grudge against the school, see full text for explanation), and once we see her slapping her son (a teenage bully) for beating up smaller kids (yet he goes on bullying them, anyway). Also, as far as we know, she has only one son, so let's assume the author doesn't imply she's pregnant.
So for now I'm assuming she feels some mental pain when she sees the students (or maybe she is just tired, her son seems like a never-do-well)
Here is the text
