My Grandfather

Exactly 9 days ago, on September 11th, we lost my grandfather.  The emphysema and pulmonary fibrosis that he fought so hard finally caught up with him.
He had had a good few days and then the Thursday before, he started calling everyone in his cell phone telling them that he was going home.  He had had a few episodes like this, where his oxygen would get so low that he would do things that he wouldn't normally.
My grandfather was an amazing man.  He was a retired "letter carrier", as he used to say, and had served in the Korean war in the Navy.  He was the most loving, caring, man I ever knew, always stopping to take care of his people before himself.
He and my Caleb had quite a bond.  Piper was born right in the middle of him taking care of my grandmother after her stroke, so even though he tried, they just weren't as connected as he was with Caleb.  My grandfather would drive from Garland to McKinney (normally a 30-45 minute drive), randomly just to see him.  He asked for him and about him constantly, checking on him and his health all the time.
I have to say, that even though we knew that his end would come soon, his passing was a shock.  True to form, when he was ready to go, he did so quickly.  My mom called me around 5:00 on the day, I was there by 7:45 and he was gone at 9:35.  We had hospice in place and they were a great support, but it's still so, so hard.
My mom and I are only children, so we were all really close.  There was a period of time when my mom and I lived with my grandparents.  I was even brought home from the hospital to his house.  So, this is so difficult.  Honestly, I feel lost without him.
