If you happen to be around a particularly cranky colleague today, be gentle. He or she may be a pollen-allergy sufferer.
Official tree-pollen counts this morning were past the "extreme" thresholds, and the grass-pollen level was "moderate."
We receive the counts daily from the Asthma Center in Philadelphia, which operates the National Allergy Bureau's local stations.
But the allergy-sensitive probably didn't need a pollen-grain count -- or even a green coating on the car -- to know this was going to be a day of torment.
