Losing a grandfather
There was always going to be more time to ask him.
He mentioned the war once, at a holiday table, in maybe four sentences, and then changed the subject and never brought it up again. You meant to ask him properly sometime when it was just the two of you. There was always going to be a better time for it. Now there is a name on a form and a handful of remembered sentences and no way to ask the follow-up questions that only occurred to you afterward.
I lost my grandpa, I lost my grandad, I lost my grandfather: the name changes and the shape does not. What people describe is rarely one missing conversation. It is a set of follow-up questions that arrived too late to ask.
This is close to universal. Grandfathers, more than most relatives, seem to carry a version of themselves from before you existed: someone who had an entire youth, a job, maybe a war, and grandchildren tend to meet only the finished, quieter version of that person. By the time you are old enough to actually want the history, he is often not there to give it.
You remember riding in his truck more than you remember what he said in it: the particular smell of the cab, the AM station he never changed, his hand resting on the gearshift at a stop light. Those sensory fragments turn out to be their own kind of record, just not the kind you can ask a follow-up question of.
The workshop only he could run
Somewhere in the garage, the shed, or the strip of garden along the fence, there is a system that made sense to exactly one person. Tools hung in an order that looks random and was not. A grafted tree that needs pruning a specific way at a specific time of year, known only because he did it every year without writing it down. A mower with a starting trick nobody else has ever managed to reproduce.
When he goes, that system does not pass to anyone. It just stops, and what is left behind looks, to everyone else, like clutter rather than the working proof of decades of one person's attention.
What you can still ask him
The unanswered questions do not have to stay unanswered in the sense that matters most. You can still ask him on a call that goes nowhere and is heard by no one, and there is something to be said for asking anyway: about the war he mentioned once, about the job before the job you knew about, about who he was at twenty. You do not need an answer waiting on the other end for the question to be worth asking.
Some people find it easier to talk to a grandfather than a parent, precisely because the relationship carried less daily weight. If that is true for you, it may be worth reading how this lands for a grandmother too, since the two griefs are shaped differently even when they arrive close together. Either way, this kind of grief has a habit of returning long after everyone assumes you are done with it.
Say what you need to say. The line is connected to nothing: no one hears you, nothing is recorded, nothing is stored.
