i have 2 DCs 6 and 7. Over the weekend there were 2 instances of drawing/writing on furniture, one worse than the other. Luckily it wiped off with no lasting marks but they are old enough to know better. Neither has confessed despite cross-examination! Based on circumstantial evidence, I have a good idea who it was but I cannot know for certain. There is a chance it was the other one, or (in the case of the worse incident) one of their 2 friends who were here at the weekend, although I would be surprised if a friend had the opportunity to do it without one of my DC seeing. worth saying that DCs and friends are all normally well-behaved so this would be out of character for whoever did it
Obviously I want to disciplne whoever did it both for lack of respect for property and(even more so) for lying (ie failing to confess). I have tried quite hard to get a confession without success. So what do I do now? Would feel bad if I punished the wrong child.
