Amusing Mystery of Everyday Life..

"When glass breaks, why don't the pieces fit back together perfectly?"

If you throw a ball through a plate of glass window, the glass will try to accommodate the force thrust upon it; it will bend. But if bent beyond its limits, glass shatters or ruptures.

At the point that the glass breaks, the glass's shape is distorted but the break is a perfect fracture - the parts would fit back together again. But as soon as the glass shatters, the parts begin to minimise their distortion and return to the unstressed state.

When the pieces return to their unstressed state, the fracture is no longer 'perfect'. Like a human relationship, things are never quite the same after a break-up.
