How can you forget you have an ancient Egyptian priest in a box? A person who no doubt commanded respect during his life, spent a few thousand years entombed, then a few decades stuffed in a box in a dusty attic. Hardly the noble ending he envisaged in his lifetime!
The famous Curse of King Tut was rumoured to be involved in the premature ends of many involved with the discovery of his burial-place, even though his remains and treasures were treated with respect.
If shoving the bones in a box and then losing them in your attic doesn’t bring down a few plagues upon your house I think it is safe to say these curses are not as threatening as some would have us believe!
