I sat down with Jet last night and tried to do my best to say sorry for saying that his biking was too slow. He nearly cried when he tried to tell me about how frustrated he was that he couldn't ring his bell in time to warn me of the guy. So there was something stuck in Jet's brain that he needed to work through, and we took half an hour and he talked about what he was feeling and thinking and I tried to encourage him to talk through it.
We cuddled a bit and he sighed happily afterward and cheerfully talked about how fun it was to bike with his friends in front of the house. So I'm happier.
