Example:
When your daughter stays overnight for her first time, spend all the time she allows, upon her return home, to know what she has done in her time away.
While I was extremely stressed out over her absence (I provided her with a camcorder. there were many kids who took game things NDS, etc, but only my daughter took a camcorder), glad to enjoy her return, I can recommend that you sit in private and review her recordings with her, asking questions
What a relief it was.
