"He said, 'Waiting on my clothes to dry,'" Royster told WAAY. "I said, 'Well, who are you?' He said, 'I'm your grandson, don't you know who I am?' and I said, 'No!'"
Royster said Love had gone into her kitchen to prepare a meal for himself, the television station reported.
"He went through my cabinets, found the toaster, a skillet, he scrambled eggs, made him a sandwich," Royster told WAAY. "He had taken a bath in my bathtub. He had shaved. I found a razor he got out of my cabinet. He brushed his teeth."
Royster called police and Love was arrested. He is being held in the Limestone County Jail on a $10,000 bond, the television station reported.
"Kind of scary at first, after I went back outside and called the police," Royster told WAAY. "Sitting there, waiting on the officers to get here, was nerve-racking. But it was funny."
