I will start by insulting her.

Kimak, boleh blajar kat luar negara tapi hanya setahun boleh lupa loghat asal. **** kat UK sedap kan? Ada putih ada hitam. Semua kau kumur sampai bahasa pun hilang. Sekarang boleh la berbahasa ikan dan kentang. Kalau tak kurang kurang ayam tikka masala. Makanan resmi diorang.

So why do this? Its called shock treatment. You can't trigger response  with compassion and understanding. At some point when she was there, she decided on something based on what she saw. We all have been in that phase where we WILL OURSELVES to accept something easily and made excuse for doing it. Some are valid life choices. Some are dumb behaviour that we enabled.
