<human>: Summarize the given text in a few sentences.

Not trying to be corny, but it's Father's Day, and I'm feeling a little sentimental.

To start- He was a very cool guy. Smart, caring, giving, funny, etc. Everything a good man should be. He fought in WWII, traveled all over the world, and called his tennis shoes his "kicks" and his Mickey Mouse Timex his "Roley", until his last days. He just died Friday (6/15) at 92 years old.

Point of the post: the last time i was with him, it was just the two of us in his hospital room. He couldn't really speak at that point, (mostly weak indecipherable mumbling) but then, he looked right at me (read: IN MY EYES) with a semi-panicked expression on his face and said, "Love is the difference". He said this over and over, clear as day. I desperately tried to get him to elaborate, but between the painkillers and an overall physical breakdown, he didn't/couldn't explain where that came from or why he was saying it.

I'm hoping the significance (beyond the cutesy obvious) will hit me one day in a glorious epiphany :knock on wood.: But in the meantime, I can't stop thinking about it. And like I said, I know the thread and even the quote are corny ("Love is the Difference" sounds like the title of a Celine Dion song, I'm totally aware of this), but they were the last words of someone who lived on this earth for 92 years. REALLY lived. YOLO style lived. That has to count for something. 

Anyway, I know it's a personal thing between me and him, and essentially it's how I interpret it that matters... but i thought it was cool and wanted to share. If anyone would like to take a stab at it, I'd absolutely love to read it.
<bot>: Grandpa died on Friday. Our last conversation, he repeated the phrase "Love is the difference" over and over. Interpretations?
