I have the problem that my filippino husband wants to call my english parents 'mum and dad' - but they would not like that at all - they want to be called by thier names and he finds that awkward, but maybe when he hears my sister-in-law calling them by thier first names he won't feel so uncomfortable - on the other hand he would like me to call his father papang - but I don't feel comfortable, when we were little we discouraged from calling neighbours or non-family by family terms such as aunty and uncle - when i first met my husbands father, before I was in a relationship with my now husband, I referred to him as 'tay' from tatay and still call him this -however we have managed to get our daughter to use all the right terms according to filippino culture as she is so young......
