If it makes you feel any better the hand written note is perhaps the real memento. Its got your grandmother's writing and thoughts on it. A real window to a deceased loved ones thoughts.

The stuff? Just materials passing through time and space.

This is also a reminder that if you want anyone to even PRETEND to care about your junk, give it away whilst alive!

At least then they have to find it and display it when you visit out of fear of being dewilled.
