That's a tough one. How can you PROVE someone was with you from almost 10 yrs ago. Even though you may know without a doubt that person was,how can you prove it. People backing you up saying "Oh yes,I remember that person was there ... means nothing. You may even have a picture,that written on the back says "Xmas 1996",means nothing.
I tried it ... I know my son was with me on Christmas 1996,and every one I know,knows my son was with us that day. But there was no hard evidence that I could find,to prove without a doubt that my son was with me on Christmas 10 yrs ago.
None of the photos had a stamped date.No videos.
It's a tough one.
