Believe me a kid can be ninja sometimes.
Storytime!!
When I was a kid, we all went to the mall to get our shopping done. Halfway in the store, my mom decided to go to the other side to get shopping done faster. I went after my mom, and my dad saw it so he knew I would be safe with her. The thing is. She didn't know I followed her. I walk silently, it's my habit. Even my small pitter patter running is kinda silent.
So my dad thought I was with mom. My mom thought I was with dad. And there's me. Distracted by something while following her until I suddenly realized she was not there anymore. I walked around and around lost LoL. Thankfully a staff saw me and brought me to customer service center to announce a lost child. Thankfully I remember my actual name. Can you imagine my mom and dad hearing my name announcement
TLDR I was a ninja as a kid
My lil brother once did the opposite of that, instead of going in the car he got out and followed my dad to work, my mom almost had a heartattack
