Monday morning, as Michael had Tovina loaded into the car and was about to head over to Kindermusic, he discovered the car wouldn't start. Seemed to have a dead battery.
After he gave up and realized that there would be no driving in the car at that time, Michael got out of the car and unbuckled Tovina so she could also get out.
As Tovina stood up, she reached up and turned off the passenger light above her seat. Then she exited the car.
Based upon this observation, we are currently suspecting that the dead battery may be related to Tovina turning on that light Friday, 3 days ago, upon exiting the car.
In summary: I'm glad we live within walking distance to Home Depot.
