Vegetarian (Pescetarian) and I ate meat on accident?? Nobody told me?? Help!?

Okay so I am a pescetarian and tonight my family and I went out to eat at this old western ghost town.......the restaurant had "rocky mountain oysters" so we ordered them.............my family forgot that I didn't eat meat (I am kind of new...almost a month) and encouraged me to eat them. They laughed because I was eating pigs ....gross I know!.........I had no idea..........now I just feel all gross because I ate meat and hypricritical.......(Did I spell that right? Lol whatev.) Has anybody ever eaten meat on accident????? Any stories or anything??? thanks!
