.  A colleague of mine came home from her honeymoon to find that her new mother-in-law had been in while they were away and the family Christening gown was laid ceremoniously front-and-centre on the marital bed!  oh that is too rich  not so subtle clue is it?  At which point I would be changing the locks and making sure MIL did not have a copy!  Not to mention a conversation or two about boundaries. How did her husband react?  He was livid. She thought it was hilarious, in that so-far-beyond-acceptable-I-can't-take-it-seriously way. They were OK with her being in there, they'd arranged that she would put wedding presents away and clean ready for them to come back to, but Things Were Said about the... little reminder.
