ended up hitting his mouth on the concrete. it was one of those moments where you see it happen, recognize the cry of pain, and are totally almost afraid to look because you know there will be blood. and blood there was. so there i was at the park, with no supplies, and no car, and a bleeding child. i tried my best to comfort him, told k to get in the wagon (thankfully he obeyed the first time for once), and took off running toward home with my bleeding child in my arms, while pulling k in the wagon. luckily, a policeman happened to stop at a stop sign
