Hello! My name is On. I'm from Thailand. My question is what is my best childhood memory?

My best childhood memory was probably when I was around three to four years old which I really don't remember from what my mom told me was that when she was trying to buy me a really cute barbie doll and I started crying because I would not want it. Instead I wanted a little buffalo doll and I cried really hard in the mall just because I did not want to get that pretty doll. Instead, I wanted the uglier doll.
