One of the trickiest of philosophical ideas must be time, and permanence. An hour can seem long or short. Four hours with an unhappy baby can seem like twenty hours, but a year later, the tiny baby is missed, and the parents would love to hold her again, but now she's off running and climbing.

Frustration hurts, but gratitude feels good. Frustration is inevitable, but gratitude takes conscious thought.
