There was this guy in secondary school who used to call me a dyke all the time until I had to ask him to stop and explained I was a guy. From then on he called me a faggot and used my correct pronouns all the time, and moved away at some point but I saw him at my uni today and the first thing he said to me was "Alex! You still a fag?"
I think that was his way of asking me my pronouns.
