Who’s wrong who’s right

So the other night my boyfriend and I were cleaning the house. Sweeping, mopping, etc.
He asks me to open the back door and I open the back door.
A couple minutes later he sees the back door open and complains that’s I didn’t close the screen door after I opened the back door.
I didn’t hear him ask to close the screen door because he didn’t ask that.
He asked me to open the back door but he says it’s common sense. That I should’ve known to close the screen door. We cannot come to an agreement and it’s nothing serious at all. But we cannot decide who is right. I’m not sure if this is the right place to post!
