I've never not used the ladies room and I don't recall ever getting dirty looks. Of course, now that I've put that out in to the universe, let's see what happens next time.
I've no idea as to why that has been the case. Maybe cuz I'm tallish... more "imposing?" <~~ that's been said. I've a "softer" ... kinda femme... sort of face? <~~ so I've been told. Or, cuz I don't really acknowledge anyone in a public restroom? I'm in then I'm out. Kinda like clothes shopping.
lol
This is a most intriguing thread. I mean, no one who looks at me could think anything else but DYKE!
So, I'm really curious at to why I've not been hassled. Of course, it could be that I have gotten the nasty glance and just didn't realize. Shrug. Dunno.
