Make that phone call

My dad passed at the spritely young age of 63 (me, in a couple of months) and we never saw it coming. I wish I had voicemails I had saved just to hear his voice again...
I call mom (now mid-nineties) every couple of days even if I have nothing to say. Just to let her know I still care and am thinking of her.
My dad died at 67. His dad died at 38 from a mining accident in northern England. I'm now 72 but I was concerned when I was reaching Dad's age. He would be 101 next month
