I was just talking about this phenomenon to someone the other day!
When I got married, I got cocktail shakers. So many cocktail shakers. So many.
When a friend got married, he got cheese boards. Cheese board after cheese board.
Another friend lived in a tiny apt. with very little wall space. For her wedding, almost everyone gave her frames. She did not have any use for all those frames, having so little space to hang anything.
