Appreciation post: Learned a cool waterfall braid from a mom at the playground

I was at the park with my kids yesterday, just watching them play. This mom next to me had a great braid in her daughter's hair, a waterfall braid that looked so smooth. I had to ask her about it. She was super nice and showed me how she does it, using just three sections and dropping one strand each time. I've tried waterfall braids before but always messed up the flow. Her way made it click for me, and we spent like ten minutes chatting about hair. It's funny how you can learn something new from a total stranger. Has anyone else picked up a tip from an unexpected place like that?
