Hello there. I would REALLY love to adopt her, but there are several problems:
1. My town is still currently full and i only let my current villagers go if they tell me to
2. I play ACNL in Emulator (I don't have 3DS), so in order to get her from your town you have to use the Emulator too
In conclusion, You may need to find another person who wants to adopt her. Sorry (Although that means i let one of my dreamies go)
