Well...... It could be forgetfullness on locking a door. Maybe your mom was cooking and she had oil penetrated in her hands, which then reached the door knob. There are many different possibilities, but this question is a little vague. This may be something you have to think about since you are living in your house.

Hope this helps :) Brainliest?
