I believe that I almost suffered kidney damage today.
Can I ask what the harm was?
I was forced to eat some non-organic food from my girlfriend's friend
Your kidneys are there to keep you alive, you were so worried about them. Next time make sure they know you can't have anything but organic food. You don't want to suffer the consequences of just any food.
I was only trying to keep a low key while eating.
I understand not wanting to be overbearing with your dietary needs. But being upfront right away will be the best thing you could do it to prevent causing your body any harm.
