Udin Ahok was forced to make a choice that no one would ever want to make: save his wife or his mother and baby.The 46-year-old Indonesian had just gone to sleep on Saturday evening when – without warning – a wall of water smashed into his house in Way Muli village on the coast of Sumatra. Panicked, he fought to reach his sleeping 70-year-old mother and one-year-old son but then he saw his wife about to drown in the swirling waters.
