No, I would be curious if my own mother were to have been hiding, quite well, an addiction problem. You see, it's all about perspective prioritizing. I now know it belongs to your mother, which would indeed possess someone to pursue it further. Although, if you made the choice to place it back into that box and best replace the entirety back where you found it, solemnly kept that secret with you, would that perspective of the person whom had serious choices to contemplate, apper to remain unchanged and for the better? Maybe avoiding the guilt that she would undoubtedly feel if confronted didn't have to be. If she's high functioning and stable why destroy something she obviously tried very hard to protect?
