Psychologists say, "Children are keen observers but poor interpreters." They see everything that is happening, but they often misinterpret what it means.
Think with me about some painful childhood memory that you have. Maybe it is about something you saw, something that happened, or something that was said. Listen to me: it is possible that you misinterpreted what happened.
For example, when children see their parents go through a divorce, they often feel responsible. They think, "If I had not been so much trouble…."
Do some work with your memories, my friends. It's just possible that your observations were correct, but your interpretation was faulty.
