I remember coming home from school one day when I shockingly witnessed my bedroom furniture being rearranged. All hell broke loose.
The moral precept to parents or future parents: Never mess with a teenager’s bedroom, at least without their permission. They are living in an internal chaos, struggling to organise strong emotions. The last thing they want is someone disorganising their bedroom. Symbolically that room could be their whole world. Teenagers don’t have many places to escape when they are home. In their continuous internal change some things on the outside should remain intact until they are ready to change them.
