Happiness is....
a new chain on my chainsaw.
Instead of pushing and leaning on a reluctant dull blade the roaring engine and whirling teeth sink hungrily once more into green timber and mighty trees are smote asunder. If I sharpen the dull teeth with a rat-tail file I never get it quite right and then the saw is skewed and pulls to one side when I am bucking a log - but with clean new teeth it can be steered with precision through any obstacle
what is your definition of happiness
