Most children who throw tantrums are two or three years old and wouldn't remember throwing the tantrum when they were an adult.
I held my breath. I don't remember doing it, but my mother told me about it later. My brother bit a stuffed animal once. My stuffed animal. He wanted to punish Mom, but he wasn't going to harm one of HIS OWN stuffed animals, lol. That was one of mom's funnier stories for us.
You should ask your parents. I will bet you they remember at least one instance of you being a brat and throwing a fit.
