Factual error: The conversation between Taylor and Michelle tells us that school is over for the day and that Taylor talked to her crush at lunch. When the boy shows up at the bakery later, he and Taylor plan to meet at 3 that afternoon; if its before 3, they should still be in school.
Continuity mistake: In the beginning, Miles is talking about how excited he is for the garage sale. When he takes a picture, Louie complains that ghosts don't show up in photos. But at the end, when they get grounded, and Miles takes the picture of the "first family punishment", then Miles and Louie show up in the photo.
