I'm just now beginning to write a series of creative nonfiction pieces, the project urged on by one of mine, "Grandpa Tom's Cane," having won the North Carolina Writer's Network Post CNF award a couple of years back. (The piece was published in SLAB magazine, Issue 4, if you can find it.)
As a diversion from creative writing, I took to genealogy a few years ago, and much of what I'll be writing I gained from the genealogy effort. But you can bet writing about family is a dicey proposition; it can be hard to write in unvarnished mode, depicting the essence of these lives as you see them, without suffering the glares of family members. But as long as you tell the truth, what's to complain about? Right?
