Disappointment

I can't send my grandmother off on her final journey on 14 December Tuesday.
I have tried to book a return flight to Taipei, departing on 13 December Monday and returning on 15 December Wednesday. However, as it is the holiday period and festive season, all flights and all classes are fully booked. For some airlines, the wait list are closed too. I managed to be placed on the wait list for SIA but the agent forewarned me that it is extremely unlikely that I would be able to get my flights confirmed.
After 24 hours of waiting and monitoring, it is confirmed that I won't be able to attend my grandmother's funeral in Taipei. :(
