So, somebody recently asked the inverse on TRP and it got me wondering: is there any way, during in-person interactions, of being amicable with a man and making sure he's comfortable and happy, yet leaving it clear that I'm not interested in him? What would constitute a clear indication, for you, that a friendly woman is friendly and nothing more?

I work in a very people-oriented job (private tutor, usually 1-1) and need to keep the environment friendly and open so the students do well, feel comfortable and return. But coming across wrong is annoying and guarding myself too much can come across as cold.
