yes, i know that permanently single people get it too.
it is an assumption made at work that i am heterosexual despite:
- never talking about any dates or girlfriends,
- rarely talking about my weekends "did nothing" 50 times of the year (occasionally gigs do come up and i'll mention these

)
- never making the over-the-top comments unlike some others of what women are attractive
- never showing any interest in any sort of thing like that.
in the 9 years i have worked there, i have never shown the slightest sign of either but the assumption is made that i am heterosexual.
the only people that haven't made that assumption (at least not to my face) have been bullies.
although my parents have made some comments "it better not be men you like"
