Last night was the worst night of the trip as far as the rolling of the ship . When it gets like this , things really move around -- cabinet doors that are not tightly secured fly open and the contents spill out on the floor . When we woke up there were papers on the floor that had vibrated off the desk and one of the cabinets had spilled out . The library in the lounge had disgorged all of its books which were spread from one end of the room to the other , plus the scrabble pieces were also dumped out .

Question: Why did the the books end up on the floor ?
Answer: Because the bookshelf had collapsed .Because the toddler threw them .Because they were in the process of moving .Because the ship hit rough water .
