"No way," Isla stormed into her bedroom. "No way in hell is she coming to join us. We've spent two years together, Anna!"
"But-" Anna cried. She shot a "Sorry about this" look at Rosa, and ran after Isla, which left Rosa to do nothing but think.
While Anna and Isla were gone, Rosa decided to write a letter to Anna:
Dear Anna,
Thanks for taking care of me. I think I'll just go into the forest and then come out on the other side- there's got to be others outside, right?
Best wishes,
Rosa
PS: Sorry about the trouble I caused.
