I mentioned in another post - dad recently had to clean out his sister's apartment and he brought home some letters my mom had written to my aunt in the 1960's. What a blast we had at dinner tonight, reading those old letters! Mom's been gone for 9 years but seeing her handwriting and "hearing" her words brought her right into the room with us.
And even though it's been 9 years, there are still times I think "Oh, I've gotta call and tell Mom ..."
As it's been said; you don't get over it, but it gets easier.
