I've had a roommate now for about eight months. She is such an Michigan State fan that she dresses in almost all college garb. Almost by definition those are men's clothes. When she and I go places together and the subject of our living situation comes up, I see an, "Oh!" look in people's eyes, and they began to ask "Sooo ... how did you meet?" Clearly a "relationship" question.
On one hand, I'm amused (neither of us are gay) and on another rather unsettled about it. My response has been more general -- she had been living for a year with her GD / boyfriend-father / GGkids and was looking for a place to live where toddlers do not reside. I had a room.
I just don't want to be put in that particular box within the circles I move, as a few women I know have "jumped the fence" as it were. I've thought about the more confrontational, "Why do you ask?" Or the more direct, "Are you asking whether we are a couple?" and go from there. What do you suggest?
This is tiring for me. I already encounter that assumption while traveling alone in "that great big motor home" ... to the point that women flirt with me. Not the attention I want. And I don't think wearing more pink will do it.
