Sounds like you have a future carpenteru2023 To correct the behaviour, starts with yours! It is obviously not the kids fault for your stupidity! I have to ask u201cwhyu201d there werenu2019t curtains to protect the privacy of your child in the first place. Donu2019t come down on your kid for your bad behaviour. YOU are supposed to be leading by example, Iu2019m on the side of the kid! You are NOT a good example, and they are just trying to find their way through the mess of you! Correct your behaviour!Then teach the right way! Start by showing the right way without any anger!Involve them in the whole process. Show how to get the right materials, show how to remove the nails without doing further damage. Then show how to fix the damage, then painting etc. Have them help, even do! Then show how to install the rods and drapery in the correct manner.To be clear, this is your fault, not the child, show them how to do it right, then they will in the future!
