(this isn't a true story, just trying to help)(maybe give you an idea)
When I was 10 I went to a theme park and was so excited to ride the biggest rollercoaster there. It was very unusual for my family to go to things like this so I was really intrigued for all the rides. It was going to take a while for us to arrive so for pastime I played games on my phone like always. As the car was entering the theme park my eyes were absorbed to the biggest rollercoaster there, I just couldn't keep my eyes off of it. As I was in the line for the ride I was happy and couldn't wait but as I got closer and closer I started getting agitated in nervousness. My stomach turned and I felt drained, the line seemed to have accelerated and then finally it was in the front of the line. (I hope this helped.. sorry that this isn't the best :/)
While many might say the fridge needs to be opened first to prepare breakfast, note that it does not say that the parents are in the house, and therefore they would need to be let in. Hence the answer of what to open first would be "the door".
