Last day of school

I met JJ & the kids at Wasabi for dinner. As usual, JJ drinks drinks three bottles of hot sake. Halfway through the dinner, I say, "James, sit on your seat...or we can get you a booster." JJ says, "he's doing fine." I drop it. Five mins later, kids are done and trying to look out the window. Merryn is trying to pick James up to look out; they're laughing. Except for one other couple, we're the only ones there. JJ barks at the kids, "stop that! Excuse me!" I say, "I think they are okay." JJ gives a heavy sigh and a big eye roll. "Well, you know better." Super sarcastic. I said, "you just did the same to me 5 mins ago." No response. We're leaving, and since he drank three bottles of sake, I want to drive. But he gets to the driver's seat first. I say, "I want to drive home." He says, "I'm already here. Get in. Let's go." I say, "no. I want to drive home." He says, "get in the car. I'm already here." I say, "no. I'm driving." By the way, this is my parents' car. I lean in the back window. He says, "what if I just step on the gas?" I say, "you'll run over my foot." He says, "oh, that's what you want?" A moment passes. He gets out; I get in. Now, silence.
