Moments lost though time remains...

Remembering the people I have lost has never been an issue for me. I have fond memories of my grandmother and aunt. Forgetting that they are gone, on the other hand, is a totally different story. I still find myself thinking, "Oh, I should show this to Grammie." And then I remember she is gone, and almost 8 year later, it still fucking hurts. If anyone knows how to make that stop, please, hook it up. When does it start feeling better? Or hurt less?
