All for a can of peaches

So over the last couple of days, he has not communicated very much. However, he can be very clear when he is not happy about something. First and foremost, he wants to do everything on his own. Friday night, he went into the kitchen. He kept going to the refrigerator, opening the door, then shutting it. He would go back to his chair. 20 minutes later, he was back. He finally sat down at the kitchen table. I showed him a can of peaches and asked if he wanted some. He just looked at me. He then grabbed the box that contained the canned peaches. Apparently, he felt he needed to open the box so he started tearing it down the side. I stopped him and I got "God Damn It", then angrily puts his hands down as though he's fed up. I explain that the box is already open and show him as I pull out a can. He proceeds to take out 3 cans of peaches. I stop him and he gets frustrated with me again. Now it's time to open the can. I give him a fork and he starts to push the fork into the can. Apparently he must think if he pushes hard enough, it will open. I try to explain if he turns the can over, we can open it by pulling the top off. He says no, we can't open it that way. So I tell him to watch and he gets mad again. Then, he lowers his head as though he is pouting. This makes me laugh. I tell him to stop getting mad and to stop pouting! Again, I tell him to stop pouting and watch. He looks up to see the peaches are open and has two cans!
