A 60-year-old Grandma from Fayetteville, North Carolina, America, obliviously drove to and from her teaching job with license plates that said WTF issued to her by the DMV.
Last July, she figured it out thanks to some help from her teenage grandchildren.
The kids informed her of the true implications of the letters on her license plate, the woman then complained to DMV officials.
The woman's plates were replaced free of charge with MILF-69, and the North Carolina DMV has offered to exchange any WTF plates .
It only took the North Carolina DMV a year to notice it.
