Well, if you feel a bit "paiseh" to use the direct approach like
going to him, giving him a fatherly hug, telling him you still love
him and you're not angry with him anymore, then you may want to try
the INDIRECT approach.
You can try any one of the suggestions below, or if you can think
of any other subtle way, that could work too:
1) "da bao" (pack) supper back for him one of these days since he
works late. If you don't feel like talking to him yet, you may want
to write a simple note and leave it on the table.
2) On his birthday, or on father's day, buy a small card or even a
present for him. Once again, if you feel that you're not ready to
give it to him directly, you can put the gift on his bed, or ask
one of your family members who's living under the same roof, to
pass it to him.
3) When you're outside, pretend to give him a call and ask him if
he knows where Sungei Gedoh (or other location) is, and say you're
lost and you need directions (it's appropriate to ask him this
since he drives, so he may know the roads of singapore well).
The bottom line is to do a simple gesture so that he gets the idea
that you're ready to accept him again, that you're ready to let
bygones be bygones. I hope everything works out fine between you
and your dad from now on.
