My mom was one who saved things for later. I only know of one time the crystal she and daddy got as wedding gifts was used - for a luncheon for my cousins bridesmaids when I was seven and a junior bridesmaid.
After I was married (and expecting child #6) and moved back home while DH was stationed overseas I started using the towels they had gotten as wedding gifts forty plus years before. Couldn't see letting them just sit there and maybe get dry rot.
Anything that I have for an extended period of time that doesn't get used, gets passed on so someone else can use it. I need to take the time soon to sort through a lot of things that haven't been used lately and find them new homes.
