Another post from the other side.
Wow, there's so many I don't know where to start, I guess chronologically.
When I was 2 or 3 (I don't remember this time) but I would wear my mom's heels. I was apparently insistent on wearing them and there is a picture somewhere of me wearing them (although my mom probably burned it after I came out

)
Just before my fifth birthday (I was born in December and this is my earliest memory) my family was visiting my grandparent out of state. We all went to Wal-mart for something, and as we walked around, I saw what I wanted to be for Halloween. I pointed at (if I recall correctly) a Snow White costume complete with make-up and tiara. I was then disappointed to find out that "boys don't wear those." This is also the first time in my life I realized there was a difference between boys and girls and wouldn't know about genitalia difference until maybe 10 (yeah, sheltered life. Religious folks).
I guess next would be that I realized women went pee sitting down. So from about 5-6 I would do the same. I can't remember why I stopped, maybe I got caught by family and was told not to, or maybe I went at school and was made fun of.

Next would be in kindergarten, and I distinctly remember this. It was the first day of kindergarten, and we we sitting at the front of the class Indian style. The teacher was going over the alphabet. Me being a smart kid (where did I go wrong) already knew it, so I was bored and not paying attention (which doesn't help when your last name is early in the alphabet and you sit in the front). I kept looking over my right shoulder at this kitchen playplace in the room (you know, the ones little girls play at) wanting to play. After being told twice to pay attention, the teacher put me in the corner for the rest of the day. Also during this time, I would prefer to play with girls toys. This stopped after I was made fun of for being effeminate and my parents stopped buying them.
Next was when I was 6 (so late kindergarten early 1st grade). I went to this girls house across the street. We were playing with toys in her room, and I talked her into playing dress up (did I say I was a smart kid, how coy to make it sound like it was her idea). Dress up was usually just me wearing her dresses and playing some make believe games. I would go over there as often as I could. Her mom caught me once, but didn't say anything to my parents (to the best of my knowledge, and thank God!).
Then 2nd grade came around, and I was insistent on playing with the girls (it got to that age where boys and girls segregated themselves at recess). The boys would jeer at me for this, and the girls weren't accepting (or it was a vocal and aggressive minority that weren't accepting compared to a silent and apathetic majority). But while trying to play with them, this two bigger girls (yeah, that age where girls are bigger) pushed me to the ground. I was so hurt I went crying to the teacher.
Then my family moved, and I didn't really have many trans-indicating moments I remember after that except that when I was twelve I was made fun of for sitting with my legs crossed in class so I stopped crossing my legs.
If I remember any more, I'll just edit them into the post. And sorry for the rant
