So Jackson thinks anything new I try to teach him is a joke or doesn’t want to listen, how do I stop that?

Example: he was telling me he was writing the letter S tomorrow.. I said you mean today? We went back and forth about 10 times and he was getting madder and madder at me. He then said he was in school yesterday so I was trying to explain yesterday we were home with Daddy, today you were in school, and tomorrow you’re going to school... but he was getting mad and arguing... I got so frustrated and told him I’ve been alive a lot longer than him and I know what I’m talking about!

I tried calmly explaining he needs to quit arguing about new things he has to learn but it went in one ear and out the other 🙄
