At one point, you see Alicia and Mike walking Alicia to her house. Then you see Alicia going up to the house. Then Mike says, "What are you wearing to homecoming"? and she says, "A Red dress I bought. Wanna come see it"? And then she goes up to the door. When this happens is, the light above her door comes on. It is NOT night time or even dawn and later, you find out, nobody is at home. If no one is at home, how did the light turn on?
