The day I started seeing my new asthma and allergy specialist. 1980. I remember lying on the table for hours while they pricked a 20X20 grid of allergens into my back and then waited to see which spots caused the most irritation. I don't remember the subsequent two injections in each arm. I only know about the injections because my mother recently reminisced about how patient I had been that day right up until that point. Apparently I lost it and got out my little 8 year old can o' whoop ass. Bet they didn't see that coming.
