My son has a secret journal that I read every week to see what's going on in his world.
What's going on in your son's world?
It's about his life and the dangers he faces.
I don't think it is appropriate to read someone else's secret thoughts. IF you want to know it might be more helpful to ask because they might get really mad and damage your relationship if they find out about your snooping. When is the last time this happened?
I did it yesterday and saw he's is dating a girl.
I would feel really hurt to know someone I trusted was spying on me. I think even kids deserve to have some private space where they can vent their thoughts in a healthy way.
