What is the text problem of the first volume of "Little Photographer" in Grade Three?

I was so careless. It's my fault that Mr Gorky is so busy that I'm still wasting his time. He can leave his job and accept my interview, but I'm so disappointed. So this time I will go to him with all my equipment!

Details: The text "Little Photographer" tells the story of a young pioneer who took pictures of Gorky but couldn't finish it because he didn't bring film. Finally, Gorky told the secretary that he didn't accept reporters, but if he was a young pioneer, he would definitely let him in. It embodies Gorky's care and love for the Young Pioneers.
