Who said private education is better?

So I just heard a conversation in the hall that went somewhat along these lines:

Where did you go for Thanksgiving?
I just went home.
Where's home?
Washington DC.
Wow, that's a long drive!
Not that bad, it's only 8 hours.
Nuh uh!
Yeah.
You mean Washington, like where the president lives?
Yeah.
That's on the complete other side of the country.
It's not that far from here.
But it takes forever to get to Oregon.
DC is on the east coast.
You're talking about Washington where the president lives?
Yeah, it's between Maryland and Virginia.
Washington?
Yeah, not Washington State, DC!
I don't understand. Where's Washington DC?

At this point I couldn't help but step out into the hallway and ask incredulously, "are you serious?" Which she was. Completely. So I found a map on the internet, and she said, "wow, I guess you really do learn new stuff at school!" New!? That is new to her?! That the President of the United States lives in Washington DC, on the east coast, not Washington State! That's the private education system at work for you. Think of that before you sign your children up for Christian education.
As the students were leaving the office the one turns to the other and says, "let's keep this our little secret". Secret, yeah right!
