I arrive at the pool. I let in one kid who's been dropped off, and a parent dropping off two more. (Stupid pool keys were added this year). One kid is already waiting inside without parent. I sunscreen my kids and an extra. Maggie gets dropped off by the piano teacher (also in the ward), and brings in a swimsuit for a kid who's not here yet. Other kid gets dropped off. Another parent arrives with two more kids. Mom who dropped off two comes back with baby, and an extra swim diaper for me. Snacks are shared. Toys are shared. Everyone has fun. 
Sun Jul 02 2017 18:35 Neighborhood Pool Dance:
I've written before about the choreography of neighborhood helpfulness (which is still going on - I went to Costco for three today). Now that my kids are on swim team, we're having the same dance at the pool. The other parents are in and out, dropping off kids. I'm mostly the only one staying the whole time, unless I leave early and get Maggie a ride home, so maybe I'm the only one who sees this. There are about 14 kids from our ward on the team.
