This summer while Daniel's family was flying to Asia, they were seated next to a Vietnamese family. Their kids were roughly the same age. Daniel's little girl was about 10 months and theirs was around 15 months. Their little girl was wearing the cutest knit hat. Well it was a long flight and they chatted as well as they could with their limited English and Daniel & Tina's...English. In the end, as they were getting off the plane the mother gave Tina her little girl's hat. Daniel and Tina protested to the woman that her little girl needed her hat. She answered that they are available on the street markets in Hanoi for the equivalent of 30 cents. Tina sent these pictures of their daughter wearing the hat.
