What makes a parent push through? What makes us just deny being sick when everyone around us has the sniffles or worse? What makes us get out of bed though the warm blankets try to entangle us?
Is it because we have to? Is it because we can't afford to be sick? Is it because there are things to do and people to see? Is it because people depend on us? Is it because a five year old depends on us?
Or perhaps the reason we will ourselves to get better has something to do with a simple smile.
