I read your message. Although you have lost money for the trip. However, your mother's health is the most important concern now. Do you agree? Let say, it was happned if you were in Japan, you would lost more such as air-tickets back to Hong Kong and you could not accompanied with your mother in this important moment.
I hope your mother will recover very soon. This time last year, my grama went to hospital because of 腦中風. Finally, I lost her at the end. Althogh she left me in the age of 90, I still miss her everyday because she bought me up since I was baby. So, please take good care of everyone you love.
I will try to get more information about the voting of your daughter and give her a vote!
