Ever since a week after the international students arrived, I have been sick with stomach problems. I had spent too many nights hovered over the toilet, ejecting my dinner. I was starting to get worried why I was all of a sudden very ill for many weaks and not able to keep food down. But my symptoms were odd, I was sick off and on, with no apparent reasoning behind my apparent food poisoning until today! One of the international students (who is a self-proclaimed expert on everything) was washing the dishes while I was in the kitchen and I caught him putting dishes away that he did NOT rinse off with water. They were covered in soap and he just set them on the drying rack. I then told him that he needed to rinse them off with warm wather to get the soap residue off. He then decided to go into one of his long winded, illogical, rants of disinformation on how its unnecssary to rinse off the dishes becuase they are 'obviously clean with soap'. I then had to interrupt him, and pull my 4 years of medical studies card, which I then explained very slowly that dish soap is not something you want to take internally, that it has chemicals on them that damage the microvilli in your intestines and make you very ill. His genious response was, "I never get sick from it, so it must be ok". I am not the only person on the korridor who has reported of vomiting in the middle of the night and feeling weak in the stomach. Unfortunately, he is too proud and furthemore, he refuses to listen to an American about anything because he holds many predjudices about the USA. As a result, tomorrow, I will go to Ã…leans and buy my own dishes so I will no longer be contaminated by his inability to properly wash dishes. Furthermore, if rinsing off the dishes is not important, than why does EVERY dishwasher in the world have a RINSE cycle (same for clothing)?
