To some this is probably a "pft, so what" moment but for me it's amazing! I dont have peanut allergies but my wife does and unless you or some one you really care about has them you'll never know how something as minute as a peanut can be a nightmare. We seriously have to ask every place we eat at what oil they cook with and we have to check labels all the time if there's a chance that peanuts could be in it. In small doses she get's hives but I have seen her get to where she got really sick, and that's pretty scary.
