When I think of my grandmother, Margaret Harper, the first word that comes to mind is frugal. She rinsed out Ziploc bags to reuse them, clipped coupons religiously, and saved every rubber band, twist tie, and grocery bag as if they were treasures. To our family, she was endlessly loving, but also a little old-fashioned in her devotion to simplicity and thrift. She didn’t have fancy clothes or a flashy car, and she lived in the same modest home for over 40 years.
