Angela - Whakatane

I feel in myself that I am missing out.
I feel in myself that I am missing out. I was working in Auckland for a couple of months I was amongst Indian, Tongans, and Samoans. Everyday they would be having conversations with each other and when it came to myself and another workmate all we could say was 'Kia ora or Ka kite' pretty embarrassed with myself. So here I am wanting to know more, also I have a 3 yr old nephew that schools me everyday and I at least want to be able to do sentences with him.
