Good grief. Tell people you want a job blogging, all you get is crickets chirping in the lonely emptiness of the blogosphere. Tell people you need answers to who did what when with a sidecar... ditto. Nada.
But mention that your day was brought to the light, warm, and fuzzy side of goodness, and they throw a monkey wrench in your gears.
