I don't know how it started or how long it has been since, but Mira and her Atuk has a secret goodbyes code between them. I don't really know what it means or if it has any meaning at all.
It goes something like this:
When it's time to say their goodbyes, either one will say 'Bye-kiiii' and the other will return it with 'Bye-diiii'. Then they'll add 'See you-kiiii' and that will be replied with 'See you-diii'. This will go on for a few rounds and they'll end it with 'kiiii' 'diiii' for a few more times.
Only then my dad will say 'Ok, bye!'; and only then are we allowed to leave or hang up the phone.
A few days ago, DH asked me about this peculiar greetings and tried to get Mira to replicate the same in their phone conversations together. She just cheekily laughs it off. But later she also makes fun of him with it by saying it wrong (bye-dididididi ~and laughs 'ahahahahaha!') and then she'll add 'apalah Ayah ni cakap macam ni'.
