The people helping you pack are carrying more of your history than the boxes explain.

Someone folding your clothes and wrapping your plates handles twenty years of your life in an afternoon, including the parts that are hard to look at directly. It is intimate work in the costume of logistics, and the people doing it generally understand that better than anyone gets around to saying.

Feed them properly, and afterward name the part that was difficult rather than only the hours they gave. If you are the one helping, handle the awkward objects without commentary and let their owner decide what to say.
