Intentions

For reasons that may be explained later, I've started reading this book:

The truth is, intentions are invisible. We assume them from other people's behavior. In other words, we make them up, we invent them. But our invented stories about other people's intentions are accurate much less often than we think. Why? Because people's intentions, like so much else in difficult conversations, are complex. Sometimes people act with mixed intentions. Sometimes they act with no intention, or at least none related to us. And sometimes they act on good intentions that nonetheless hurt us (p. 11).
