Vinegar can be utilized for many things. And it can be safely used for a variety of cleaning purposes around the house. The same goes for hydrogen peroxide. But together, they are toxic. Remember this when it comes to people. Someone can be a great friend, coworker, or mentor to another person, but not be the right fit for you. And before you throw out the word “toxic” to describe an individual, ask if you would want them to use that word to describe you. You both could be good individuals with good hearts, great intentions and motivations, but something about your chemistry when combined just doesn’t work.
