My sister thought she was a boy when she was 7-8 years old. She went shirtless on her bike and acted like a boy. She eventually got over it. Shes 50, been married for almost 30 years and has 3 children.
I was such a tomboy at that age too, riding around on my bike with only shorts and boots on. My parents let me be me, but made sure I knew I was a girl and that could never change. Married to my husband for 17 years now...
Does she still ride shirtless on her bike?
