In a meeting I've asked someone a question and in response she said:
I'll let you know when I find out
From her tone, I know that she didn't mean to be rude or anything, so I just want to know what a native speaker will get from it. Will you consider it a normal sentence, or rude or even funny?
Clearly, I am not a native English speaker, but I've expected to hear something like:
I will inform you
Or something like that.
