Classes resumed today, after what feels to everyone like a lot more than a week. It isn't just Holy Week. It isn't just Obama's history-making speech and the distressingly petty and defensive reactions it's drawn in some quarters. It isn't just the buds on trees sneaking open... Maybe it's all the troubling thresholds we've recently crossed: $100/gallon oil, $1000/oz gold, and, just after the 5th anniversary of the invasion, the 4000th American killed in Iraq. Recession or depression? $4/gallon gas and 95 more years in Iraq under a President McCain? April's the cruelest month, but this year, with early Easter and the early change to summer time, it seems to have come early.
