I dont think I would wait for her to come to me. My daughter is 13. I have always subscribed to the idea that I would not put my daughter in a position to lie to me. If I knew she did something, I would say "I know you didnt do your homework" Never ask her "did you do your homework?" If you already know the answer, dont set up the possibility for a lie. The idea is not to test them. It is supposed to promote honest communication. I think it will be an adjustment having you home and parenting full time again. I would tell her that I know she disobeyed me. That is was not acceptable and now that you are home, there will be consequences in the future. Its just a tiny piercing. She will grow tired of it and grow past the phase!Good luck
