This happened about a year ago.
After receiving very negative feedback for an essay I’d worked really hard on. I was quite worried about what grade I was going to get and very upset. I bumped into a male peer and instead of asking me if I was OK he simply asked “has your boyfriend dumped you?”. Bearing in mind I had never spoken to him about my boyfriend for him to have any reason to think my boyfriend would dump me. In fact I didn’t know him very well at all and had never even mentioned I had a boyfriend. Needless to say it did not improve my mood!
