Completely lost!

My date book is missing and I am completely lost. For the life of it I can’t remember when I last had it or where that might have been. The really bad thing is that there were several important items in it. My date book was like a mobile office and stored everything from communion invitations that required a response to cards from business associates. I feel really stupid calling everyone under the sun up to request they remind me of various appointment but I guess that is what I am going to have to do. Sadly, I have never gotten on the PDA bandwagon but I guess I am going to have too. This problem could have all been eliminated if I had a back up copy on my computer.
