Picture it:
Front seat of the bus. Naugahyde smell, rowdy pre-teens chattering excitedly, morning sun shining brightly over the dew-covered cities of the valley.
Our hapless hero sits happily texting a friend about plans for a future road-trip. Suddenly his phone slips from his fingers. No biggie, right? Normally yes, but today is different. The phone - insert slo-mo sequence - falls to the floor, bounces under the barrier separating the seat from the bus stair-well, clatters down the stairs, and slips through the crack between the stairs and the bus door meeting its doom at 50 mph.
Later, pieces of the phone would be found scattered along the side of the road, where they would be collected and taken to their final resting place - the Verizon Cabinet of Shame.
End-note: Phone warranties do not cover falling out of a bus.
