When we first married I had a little address book, and the majority of the names in there were included on my Christmas card list. As the years went by, one by one Aunts or Uncles would be crossed through until eventually the little book just made me feel so sad and I rewrote my Christmas list into a new address book.
After a while, of course, this list made its way onto a computer and most years lately there have been further deletions, but now these are friends and relatives in our own generation. And somehow it's worse, because when they are deleted, they're not simply crossed through, but they disappear altogether, into the ether, as if they'd never been on my list to begin with 
It is very upsetting, isn't it? I completely understand how you feel Urmstongran
