My grandfather always talked about grandmother being there talking to him. I believe she was.
Zanna, I would not doubt for a minute that your father was there with your mother. 
Its okay. Many times I see folks sorta leave before the body does. I always have the idea that they are all ready with the angels. We just have to take care of the body while it does its natural thingies.
Oh yes, he was there.

She and I always joked that when she left...she and he would
just show up, holding hands, and she would just say... Bye...
and they would just fade away.

We would laugh at that scenario until tears came out of our
eyes.

But, when it did happen...it was so beautiful and so very
tender. I woke up, hearing their song as clear as if it was
playing in stereo... Love Me With All Of Your Heart by
Jerry Vale. I knew. It was 6:01 a.m. 6/1/2007.
I went, sat in a chair with my cellphone in my hand. 9
minutes later, the phone rang. She was gone.
