How sentimental are y’all?

Kind of a soft question, but I went to an estate sale this weekend and was kind of floored that these folks’ survivors (I know they had several children and grandchildren) were prepared to just scatter all this (very nice and presumably heirloom) stuff to the wind. I know I’m more sentimental than the average bear, but what are y’all’s thoughts on family heirlooms, making space in your home/life for this stuff? Assuming it’s actually nice stuff and not post WWII crap. For clarification purposes, I’m a Millennial.
