I have been feeling a bit under the weather. I have spent the past few days in a skirmish with the common cold, scratchy throat, and low-intensity headaches. No matter how much I try and take precautions, this slump happens every year like clockwork — once, in late December, when the winter sets in San Francisco. And, then when summer kicks in around June. The general listlessness means I don’t feel like doing anything — and that should explain the silence here. I am on the mend, though.
