So, one of my fourteen year olds wishes to paint their room black. I think they are going through a goth phase or something, as what they wear is changing too. I told her no because when we first moved in to our new place about 2 years ago, we let her paint her room yellow after her insisting that she would still like it later(It's a sort of lemony yellow). She promises to do all the work herself, but the likelihood is that either me or my wife will end up doing it. She got very upset with me, and so I'm conflicted. Should I let her paint it?
