I asked my mom about this a while back, she said she doesn't remember me crying much as a kid. Described me as a very 'calm' baby. She said when I got frustrated about things I would look like I was going to cry. Maybe that should have been an indication of how frustrating and overwhelming I found the world?
I do remember crying as a kid, but only when I was alone, and I tend to cry silently.
Once, when racing my sister to our bus stop, I fell and cut myself. I remember calmly discussing with my sister if I should go to school and go to the nurse or go home. Our neighbor came along and told me I needed to go home and have my parents take me to the hospital, I ended up getting 6 stitches, I still have the scar. I must have been 6 or 7.
Never had anyone close to me die (didn't really know my grandparents), I don't know how I would react.
Never cried while watching a movie, whereas my little sister will cry over any movie with a remotely sad incident, completely baffles me.
