Derek takes our family to a 2 day trip to Hamilton and Waitomo cave. We really enjoyed the time together which is the highlight of my New Zealand travel. We also deep involve in his social life and experience the local authentic culture. Although my dad and Derek cannot speak each other's language, they almost communicate every morning. Two irrelevant parallel topics walk in harmony and if you only see the body language and facial expression, you will think they are talking something. Thanks Derek for bring so much laugh for our family every day!
