I was doing some work in a summer school, tutoring in a language. On my first day, a male teacher there who I'd just met asked me my name and what subject I was teaching. I replied and then he said 'And how do you say you're beautiful in that language?'
I was embarrassed and didn't know what to say, he just laughed and then walked off, never saw him since.
I'm sure he didn't mean any harm, I should take it as a compliment, it was just a bit unwanted and especially in a professional environment.
