Hmm, in terms of forums such as this one, I do not even think if one person is man or woman. Sometimes when the avatar is way too feminen (ffs how to you spell that word?) I might think for a moment "girl" but that is about it.
In RL I can remember only one time I confused one person for the opposite sex. (though I am sure there were more occassions. (btw don't mind my spelling today)
I remember it like it was yesterday. Both on vacation in a "camping site" and me as a young 12yo going to the public toilets with a HUGE roll of toilet paper and smile of "relief...soon". There a guy same age was waiting outside the building looking at me. Short hair, same height. Smiled at me and said hi, I sad hi and talked for about 30 sec. I was in a hurry to go inside the building and thought it was a bit wierd for him to be so friendly. After I finished and exited (yes exited) the building there he was again. Waiting. Apparently the kid's father was still inside. Smiled at me again and then a man said "Zoe, let's go". WTF? She is a girl? Relief! :bleh: The next 10 days were amazing, spending all day (from 9am to midnight) together, biking, talking, reading comics, playing. What a great girl and how much fun we had together. She was very beautiful too (bonus). So the last day I was there she gave me her telephone number, and my mother hold it so that I do not lose it, and she lost it. I never saw or talked to her again. Not knowing her last name didn't help either.
I will shut up now.
