This is where you can tell stories of things that happened to you when you were little/younger! They can be funny, happy, sad, scary, heartwarming, ANYTHING!
You may talk about what age you were AS LONG AS it was indeed a long time ago. But I don't think we should talk about how long ago it was. So you CAN say, "When I was five years old. . ." but you CAN'T say, "Ten years ago," or "In the year 2000" as it would be easier for people to guess your current age. @Hanna_Brassheart is welcome to tweak these rules as needed.
One day when I was pretty small, my mom was making spaghetti, and one of the noodles had fallen out of the pot and onto the stovetop. So I tried to pick it up and put it back in the pot. You can probably guess what happened after that. . . I burned my fingers on the stove. It was kind of miserable at the time, but it's funny to look back on now.
