candy jars filled to the brim . . . with memories

During the holidays I fill our candy jars with cookies and well, candy. . . but then they go back to holding our memories.  The jars are filled with matchbooks, champagne corks,  old keys, foreign coins, subway tokens, ticket stubs. . . 

It's almost impossible to find a restaurant that still gives out matchbooks...they are the perfect little souvenir to remember an evening.  Or tickets...we have saved every ticket to every concert, Broadway show, horse race, baseball game and every sporting event you can think of...Circle Line tickets, The London Eye, the Eiffel Tower, museum buttons...and before you know it all we'll do is show them our smart phone as we enter.  Tickets will become a thing of the past and they already are in many cases.  

I love technology, without it we would not have many things...blogs being on the list, but I'm a little sad when I see our jars filled with things that may become obsolete.  Does this bother anyone else?  I was just wondering.
