We just got Pranked in a good way

SO - last year my daughter's best friend, Sarah, went to Korea to teach English there.  She contacted us at the end of last month to ask about whether we might be willing to put up a Korean girl who would be visiting the States and was in need of a safe place to stay.  We agreed to it for a small fee to cover her meals and spent the last couple of days cleaning out our guest room so a stranger could come and live with us for a month, trusting Sarah's judgment that she would be okay as a houseguest.  We set it up with a tea basket and hot-pot in the room and even put a chocolate on the pillow, kind of getting into the "I guess we're a temporary bed-and-breakfast" thing. We were told she 'speaks English pretty well' and had her own transport, and that she'd heard about my daughters and was looking forward to meeting them.

The day passed and we were growing concerned that we didn't have contact info for the girl, who was supposed to have arrived in the country.  We put a sign out at the end of our driveway with her name on it, lacking any other way to contact.  We couldn't reach Sarah, but she'd said she was going to be away from the city where there was spotty wi-fi at best... As it grew dark we fretted that there was some lost sojourner out there somewhere, as our house is difficult to see from the road.

Then a car pulled up! Hoorah!  At last! Then Sarah got out! Wait........what?????  SARAH, what the HECK are you doing here in the US instead of Korea???? And where is the mystery guest???? 

Turns out the Korean girl she'd told us about did not exist except in the form of Sarah herself, who 'speaks English pretty well'.  The name she'd made up simply meant 'my darling' in Korean.  My daughter is over the moon - her best friend is miraculously here in our house and will be with us for a month.  Well done, Sarah, well done.
