There are situations in which you think you are protecting your child, and then you realize that, without wanting to, you have entered someone's pre-prepared game. And that every next move is no longer just a parental decision, but part of someone's plan.

TL;DR
- Parents may believe they are protecting their child.
- They can inadvertently become involved in someone else's plan.
- Parental decisions can become part of a larger, external strategy.
