Relics are symbolic, they are like a material embodiment of something spiritual. It works very well. People often try to seal memories with things. For example, a ticket to a concert, souvenirs from traveling, a pebble from a beautiful place. (The mug that Lisbon gave to Patrick)))) is more often just a photo now, of course. But these things hold the emotions of the past and you can feel them anew by going through these things.)))
I personally keep my grandmother's tea set, not to use, but as a memory, and actually a lot of other things)))))
