Hey gazzy! I've been thinking of my Gram alot lately too. I think it must be the time of year. She was my soul sister and I will always miss her.
About going to the cemetary? I do understand what your'e saying. After my Mother's funeral, we went back up to the cemetary and to see her name on a marker, as her stone wasn't there yet, was like a slap in the face. It proved that YES, she was really gone.
Then, when her stone was placed, it was so surreal~ there it was in bold engraving; her name, death date, etc. How could that be?? It took me many months to accept it and now I can visit their sites and not totally fall apart. I keep thinking my Mother would say "get on w/your life, I'm w/Dad now and I'm ok* My G'parents' graves are next to my folk's, so I don't have to travel to diff places.
Just remember your Grandma loved you in such a special way. I truly believe a Gram's love is special. Take care Gazzy.
