When a teen demanded an elderly woman's car keys, the Washington, D.C. grandma cautioned the young man. Unfortunately for him, he didn't heed her warning and was hospitalized as a result.

An unnamed 15-year-old boy got a brutal reality check when he tried to carjack an elderly woman, who was known by her neighbors as "Grandma." Sadly, the Washington, D.C. grandma was on her way to receive chemotherapy for cancer when the incident unfolded in her 22nd Street Southeast neighborhood on a Friday morning, according to The Blaze.

It was approximately 8:30 am when Grandma was approached by the carjacking teen, who claimed to have a gun, according to the Metropolitan Police Department.

The 15-year-old suspect entered the senior citizen's vehicle "demanding keys" to the car. But, rather than caving to the teen's demands, Grandma refused to be carjacked.

Instead, Grandma offered the young man a word of caution. "Next thing I know, he walked up talking about, 'Give me your keys, I got a gun.' I said, 'Baby, you better shoot me because you're not taking my car,'" the elderly woman explained in an interview that aired on ABC 7 News DC. She declined to show her face on camera.
