Damn auto-correct. (that’s always my excuse.)
Auto correct does suck.
“Kingston” instead of “Kingdom” seems like a pretty obvious auto-correct instance to me. She may have hit a wrong key then didn’t proofread. It happens to most of us, occasionally. (Yesterday I sent a message about having a “fiend” in my house. Oops, that should have been “friend.” )
Surely no one thinks that she doesn’t know the difference between the two!
