It all started when I was in high school. Well, it probably started before then, but this was when I began to notice. One of my good friends had been claiming that he knew how to make the best ever guacamole - so one day after school, he came over and whipped up a batch to prove it. And oh, was it good. We sat and devoured the bowl with tortilla chips (my favorite salty snack to this day), and then I had to run off to babysit. All was fine and dandy until an hour later, when I was laying on the couch with severe stomach pains and nausea. Luckily the two-year-old boy was easily entertained by the TV, and did not realize his caretaker at that moment was incapable of doing mostly everything. I figured I was just having a bad (really bad) stomachache, which was not out of the normal for me. A few hours later I was feeling a bit better, so I never made the connection between eating the avocado and how I felt afterward.
