boomerang: a kind of throwing stick that, when thrown correctly, travels in a curved path and returns to its point of origin
Like an Australian boomerang, Carrie left last week and returned this week.
Trading "hey why not" for "there's no place like home" may have been in her mind, but she had no ruby slippers to magically whisk her home, so she had to endure the 20+ hours in a plane, TWICE!
Speaking of appropriate phrases, let's don't forget "it's a woman's prerogative to change her mind".
Welcome home, Carrie!
