Well, that theory, which isn't particularly backed up by MSM, but does sound possible to me, has her running over to her mother's place, red work shirt in a bag. She plans to eat dinner there, sleep there, take the car in the morning, and stop by her boyfriends house to give the dogs their morning walk.
And...she's attacked on the way there.
This theory doesn't explain the glasses/contacts being left at her boyfriend's house. But, it's easy for me to believe that she had an extra pair of glasses.
