Rudest ever!

We were eating dinner. Merryn didn't want to go to her chair. She wanted to sit on JJ's lap. I had cut up strawberries for her, but she was eating the strawberries off JJ's plate. Then she demanded mine. I said she could have them if she went to her seat. JJ was asking her if he could put her in her seat. I was trying to get her into her seat too (asking her to go there). She demanded more strawberries. JJ got the container. I said, " let's wash them." I took some to wash them in the sink. When I came back, he was giving her ones from the container. I said, "please, can we have her eat the clean ones?" He gave her more from the container. I said, "JJ, you are ignoring everything I say. I tried to get her to go to her seat, and I offered to switch my whole strawberries for her cut ones of she did that. I asked her to eat the ones I washed, not the ones from the container. You gave her ones from the container right after that." He said, "how can you care about dirty strawberries? You put cheese with raw chicken!" I said, "what???" I have never, ever done that!" This escalated until he said, "You are the rudest person I have ever known. You're annoying."
