S-26 vs S-26 Gold

This afternoon, I was driving back to the hospital after buying some stuff. I was almost at the hospital when I got an SMS from Michelle to buy a can of baby milk. We’re on a breastfeeding regimen but we needed something to supplement for when we were at home.  I doubled back to the nearest Mercury to buy one. When I got to the hospital, the nurse told me I got the wrong milk. It was supposed to be S-26 Gold, not the S-26 that I had bought (what’s the difference?). So off I went back to Mercury to swap it with the real stuff. It wasn’t too far but the traffic always make drives longer. Wish I had the Midas touch.
