Keep birth announcements

I am not a card keeper (unless it includes a heartfelt message) but a word of advise.......hold on to birth announcements you get in the mail!  They will come in handy when you are about to visit a friend and can't remember his/her kids' names.

You might be wondering where you should keep stuff like this?!?!  I have a photo box with memory stuff in it.  It includes souvenirs, concert tickets, notes, birth announcements, etc.  When the box gets full I go through it (which is actually fun) and purge anything that doesn't drum up positive memories.  If I can't remember where I got it or why I kept it, in the trash it goes!
