The new Evan Hartmann wondered how exactly Lady Storitz ended her miserable life. He also knew that even though there was a valid reason in her doing so, in the form of his devilish husband--- there must be some precursor to the event. Something that tipped her over to the edge.
The final straw.
The rain patted down the pavement and it splashes. Seeing this, Evan was reminded of something. An object in action will remain in action unless met with a force to halt it. Similarly, an object that remains at rest shall remain at rest unless met with force to move it.
Such is the law of inertia in physics, and possibly, the law of all inertia as well. Usually, things are stagnant, and so are people, unless a force drives them to an abrupt change.
