i do not really have any problems with father in law, coz he is the quiet type and we seldom talk. In fact we never talked more than a sentence each day, except just call him good morning!!! But initially i do thought that he do not like my son coz when he was a baby, he seldom hold him or play with him. thought grandpas will really love to play with grandsons???
On the other hand, my father really loves my son and due to the time spent together everyday, sometimes my son will call me " gong" instead of mummy, too used with " gong" around!!!
