If you could spend 15 minutes with anyone, living or dead, who would it be? Why?

Not sure why but I would spend 15 minutes with my younger self if that is possible. Like, I want to spend 15 minutes standing beside my 7-year old self that was so curious and decided to climb on a chair, open the kitchen window and look down at the ground floor from the eighth storey house that I used to live in. We probably won't talk. Just standing next to each other and have the same thoughts go through both of our heads at the same time.
