Encarna Alés was taken out of school when she was just 8 years old. Now 74, the Spanish grandmother is still unable to read or write.

Though she has managed well enough, Alés loves to call her friends and family, and her inability to read people's names in her contact book has proved difficult.

Thankfully, she has a dedicated grandson who developed a creative solution for her illiteracy—and he's been maintaining it for many years.

Since Pedro Ortega was 11 years old, he has been doodling small illustrations to correspond with his grandmother's contact phone numbers. This way, she can identify the number based on its drawing, rather than its name.

Ortega has been adding new drawings to his grandmother's phone book for the last 20 years.

"Every time I'm back home, I sit down and add new drawings for her," the 31-year-old told BBC. "It's become something special between the two of us."
