There are many like us who didn’t have time to calmly pause to collect wallets and purses as we fled our homes with wet towels over our faces to avoid choking (窒息) to death". Human Services Minster Joe Ludwig has apologized for the inconvenience and says all efforts are being made to ensure people get the help they need. "I don’t know the precise details but we are sorry if it did happen," Senator Ludwig said. "We have instructed Centrelink to take the lightest possible approach in confirming identity."
