That makes sense and eliminates that option, certainly. Since we only have a few lines, we’re making a lot of guesses. Some of them will be wrong.
I still feel the opening should begin closer to whatever is causing Julie to reflect in this moment. For example, Stand by Me doesn’t begin by recounting a sequence of events from the moment Gordie wakes up until he is reflecting after reading the headline of his childhood friend being killed. Is it the house, like the newspaper headline for Gordie, that is causing Julie to reflect on the event and the past or perhaps something or someone she is going to meet inside of it? Is it important to start the story at the start of her day for some reason for the reader? Is the note she left foreshadowing something?
I remember an article I read that described several of the reasons authors feel like they have to start the story at the beginning of the day/waking up. This feels like it fits one of them. I’ll see if I can find it tonight and I’ll reply with a link.
If the story is working for your readers, the opening doesn’t have to be perfect or follow ‘rules’, but I suspect you feel something is off only because you posted this topic question.
