Good golly. The woman is 83 years old. She probably doesn’t remember what she had for supper last night....much less, a conversation she had with a fake African.
Even more...this is elder abuse. If she was my grandmother and the crowd came after her, I’d tell them to back the Hell up. I’d ask grandma if she felt like apologizing. If she didn’t, I’d let the crowd know...and then tell them to “Get off my lawn.”.
