When we swat a mosquito, we don’t necessarily have any hostility toward it or its actions; we are indifferent. We are merely getting rid of an annoyance. That may be our attitude toward a great many things in the world—we don’t give them much thought, and we don’t care that much, if at all. For us to care about something, it must have some kind of emotional connection to us. We must have a reason for feeling something, positive or negative, about it and how we interact with it. Sometimes our indifference is affected for a purpose, sometimes it is genuine. Sometimes indifference is intentional, while sometimes it is due to a lack of awareness. Sometimes we are aware, but there is no emotional connection—there is no common frame of reference that would make us care. We can know something or someone well but still be indifferent due to how little they are involved in our lives. And, in the same way that we should be aware of why we have strong emotions about something, we should be aware of when and why we don’t.
