The hard thing about happiness, joy, or contentment is how short lived it is. You know some negative thing, occurrence, or person is going to stick a pin to pop that bubble. Or, another theory, is it at all possible that we just find the happiness a bit boring ? Actually even a lack of laughter, admit it some of the darker negative folks crack you up. Maybe some of just know deep inside the negative is definitely around the corner. Another possibility, is the expectation of happiness supposed to be constant with never a bump in the road ? Does my personal definition of happiness need to be adjusted ? Nah, at least we know unhappiness will always be there. Enjoy the a Day !
