The Rosemary debacle

So the other day at work I was designing this great container for a customer, she had decided on a great rosemary topiary spiral of about 2' and I assembled some purple leaved ornamental peppers, some purple heart, violet nemesia and lysimachia to accompany it. I kept taking swipes at the rosemary to release it's scent (customers can't fight the urge once they smell it). SO- on the way home I went to wipe away some fallen mascara I spied in the rear view mirror. Soon I began watering, sniffling and crying. At this point I had NO idea of what was causing it. For almost 3 hours I was a total blurry mess. I had washed my hands 3 times BEFORE I tainted myself- another 4 before I took my contacts out... Ouch!
