At 10 I was riding my bike into town, 2.5mi, on roads with limits as high as 50mph.
Sometimes I’d ride my bike in on a Sunday, get a lift home, skip the bus from school, walk to my friend’s house, play Nintendo for an hour, and ride my bike home. I’d get there the same time the bus would drop me off and I got to play Nintendo for an hour.
Subnets…do you mean VLANs?
