Hogs

Sometime after he left the navy and before he married my mother, my father owned a Harley-Davidson motorcycle - a HOG. While digitizing their photo album, I ran across a photo of him with it, so copied it and have it in a frame on my dresser.
My daughter, Chris, and her husband, Randy, now own a HOG, which they ride every opportunity they are given. It rested over winter in their garage, covered by a blanket. There was a short discussion about whether or not it was acceptable to cover a HOG with a PINK blanket; think of it! A HOG covered in pink! I cringe at the thought of it.
However that may be, a few Sundays ago, I suddenly had the urge to send Chris and Randy a copy of the photo of my father posed proudly next to his Harley. So off it went via e-mail. Shortly after, I talked with Chris and she said she was pleasantly surprised to receive the photo. She and Randy had been talking about the Harley on Sunday - the same Sunday - and she remarked that she'd love to have a copy of her grandfather with his Harley, and the next day, there it was.
Who do you suppose whispered in my ear telling me to send the photo?
