Not a strep, but I remember getting sick with something. Go to docter, go to apothecary. All the while grumbling I had work to do and this really was messing with my schedule.

Walking home, with pills in hand, I somehow got really sick very fast. That's when I realized this might have easily killed me 70 years ago, and the antibiotics I was holding were a small miracle. All that grumbling was first world problems.
