I was eating lunch with some coworkers today, and I ordered a burger with bacon, blue cheese, and no bun. One of my coworkers asked why I didn't get a bun, so I told her that I don't eat grains. She replied, "But they've got more than one kind of bun. Just get wheat or rye or something."
I was about to reply to her suggestion, when another coworker asked why I don't eat grains. I decided to take a chance and started explaining the science behind why grains are unhealthy, mentioning gluten, lectins, etc., but his face grew more and more confused, so I switched tactics and said, "Grains make me sick."
He looked at me blankly for a second and then said, "Ohhhhhhhh...That would be hard!"
