I Said I Didn't Want to Know What That Was

Last night at dinner we went to a restaurant called Sigue La Vaca (Follow the Cow). It had a salad bar and then a huge grill area where you can get as much meat as you want. I didn't know what most of the stuff was called, or even what it was for that matter, so I just pointed at stuff I wanted put on my plate. While traveling abroad I like to be an adventurous eater so I can get a complete taste for the culture, but I do have my limits. Most countries use a lot more of the animal than the US, so you must proceed with caution when eating meat. I asked for a piece of what I thought was chicken as it had a lighter color but upon my first bite it was immediately clear that it was NOT chicken. It did not taste good and had a creepy texture. I expressed my dislike of it and said, "I don't know what that was, and I don't want to know." Leah said, "yeah, that definitely wasn't chicken." Then her cousin chimes in, "is that tripe?" Leah: "yes." I responded, "I said I didn't want to know what that was." Why on earth would you tell someone that they had just eaten tripe? Why? It was all I could do to keep the rest of my dinner down.
