Thank God there is someone else that gets it. Tell anyone from age 2-115 years of age NO! If they have any stones about them, they will do whatever you said NO to, regardless of repercussions. My daughter has found pens and markers and written on the door frame in the house and on the couch twice. She knows it is wrong, she knows she's getting a whipping and we have hidden and moved all the writing utensils. Guess what, she stacks stuff up to get on the fridge, cabinets, figures out how to get into the drawers and does it again, knowing the consequences. Not quite the same as drugs, but it is what she wants to do and she is ok with the consequences. I can only step it up so far and only hide things so well. What can I say, she is my daughter.
