When I was 4 1/2, I walked to kindergarten by myself 8 blocks away. Never was a problem until I bumped into a dog who scared me. The owner drove me home. The owner was a friend of my mom’s.
Mom walked me to kindergarten on the first day at age 5, showed me the bad intersections, after that i was on my own and had a key to the house.
Put dinner on when I got home.
