These sentences that make part of the beginning of a short story are written in the A, first person. The first reason is grammatical; because the pronoun "I" used from beginning to end of the excerpt is the main characteristic of the first person singular. Second, in the stories written in first person, you do not have access to any information from the story save the one the main narrator is giving you, which means your view on the story is limited only to that one person who is narrating the story. All you will experience from the story will depend on that first person singular narrator who is witnessing the events and retelling them to you from his/her perspective.
