Another little kid ran over to Henri and hit them? smacked them bonked them? poked them? Made contact of some kind. Henri was not phased and I didn't see what happened, from where I was it just looked like the kid walked past them. The kids parent apologized and made their child come back to apologize to Henri too. While I appreciate that the parent was aware of the situation and trying to teach better behavior, it was so clear that the little did had no idea what they were saying sorry for.
I talked about it with Henri more when we got home and explained how we use gentle hands with each other and we don't touch other people without their permission. That it's okay to tell someone that you don't like the way that they are touching you. How sometimes it's hard for little kids to remember this and that they are still learning too.
I feel like we've reached a point in parenting where things get a lot bigger very fast.
