After his death, my family went through his belongings to sort out what people wanted and what should be included in the estate sale.
In the living room, there was the obligatory wall-sized, floor-to-ceiling bookshelf. You probably know the one from your grandparent's house. Filled with the kind of books you'd expect: encyclopedia, book of the month, condensed versions of great books, random novels, et cetera.
Rifling through the first book, I noticed there were notes written in the margins. About every 5-20 pages. Sometimes short, sometimes longer. I smiled and carefully set the book aside.
But the next one had notes too. And the next. And the next. Almost every book in the entire bookshelf.
My grandfather was a quiet man by the time I knew him. Of the ten words over dinner sort. But whenever I find myself reflexively going through Facebook or whatever other quick fix the internet affords me, I imagine him coming in after a long day of physical work, opening a book to his bookmark, and reading and noting a few more pages. Every day.
Then I try to be more like that person.
