I'm sure i've had earlier memories, but I can't recall on a time line what happened before one.
It was my first day of kindergarden,so I was about 5, and my house was literally around the corner from my Elementary School, and my dad had always had his motorcycle, but I had only ever sat on it, not ridden on it. That day he surprised me by giving me a mini helmet, and driving the 30 seconds (literally) to the school. I got to walk in with my motorcycle helmet, and I basically felt awesome.
Its disctinctive because: I was on a motorcycle as a young child, and I strutted in with my own helmet!
I think my personality was basically the same, because even though I was super excited, I didn't brag to anyone about it, and unless they asked, I didnt even explain about the helmet. I didnt want to cause drama. Chill from a young age.
Another cool memory, I'm pretty sure it was the same year, not sure. Just as an add on - my dad had this giant Ford Excursion truck, and my dad used to let me sit on his lap and he'd press the pedals and I'd drive around the school parking lot on weekends. But I wasn't very good, so I ran over every single curb. He had a truck, it could handle it. I wasn't worried.
