My grandparents—Vanaema and Vanaisa, we called
them—came from the tiny Baltic country of Estonia, and for
all the years I knew them, he could hardly hear and she could
barely see. Vanaema was in fact legally blind, and yet she
knew, by feel, the exact location of every dish in her kitchen
and every book on the black metal bookcase in the living
room.
For a treat, we'd sometimes pile into their black Chevy
Nova for a drive around town: My grandfather at the wheel,
my long-legged older brother in the front seat, and Vanaema
sandwiched between me and my little brother in the back—but sitting so far forward she
was practically in the front. That was her preferred perch from which to see the world—a
blur of images rushing past, no doubt. From here, she managed to "back-seat drive,"
scolding Vanaisa in Estonian. "Kuule, Juku!" (Hey, John!) she'd chide him, "slow down,
not so fast!" Somehow, even with her failing eyes, she could always tell when he'd
missed a turn or forgotten to turn on his headlights. from "What My Grandmother Could See" by Teresa Herlinger
