When I was 3 my mom went back to work so her friend down the street babysat me during the day. Once I’d get to her house she’d shove me and her two boys out into the backyard to play until my mom came back.
The play set in the back yard was a 60s VW Bug filled with shattered glass from all it’s windows being smashed in. This was before safety glass, so I’d have cuts all over my arms and legs, and glass imbedded in my skin. Luckily they had Bactine to spray in my open sores if I cried.
