I was just thinking about my trip to Phils and the people I met. Because I was with Charie and she called her mother 'Nanay', I also used this way to refer to her too which I think went down well, her sister I called 'ded chi' which I think is a more personal way to refer to her.........please correct me if this is not the case, but my Mahal said to use this term.
We spent a lot of time in the company of her uncle too, and because of the way we go on together, I called him Uncle.
I think for me and the way I tried to fit in with all of the family I met, it was not out of character for me to use these terms of familiarity, I think it was appreciated that I 'want' to be part of their family and so I was made to feel at ease all the time.
