The current cabinet is quite a bit too small, plus the shelves are starting to sag, so I worry that it isn’t going to hold out for the long run.
What’s nice about that system is then you tell the kid that if anyone asks, you just say “I don’t know where the keys are.” It gives the kid a feeling of responsibilty AND if the kid’s friends really want to drink it let’s him ‘blame the parents’ instead of saying “no, I don’t think we shoud” it makes saying ‘no’ to the friends much easier.
