Ah, yes.
Tampo
In Philippine culture Tampo refers to a range of behaviors in which a person withdraws his or her affection or cheerfulness from a person who has hurt his or her feelings.(From Wikipedia)
We Brits often describe it as sulking, but actually that's not quite correct.
It's a deeply cultural behaviour that in the Philippines is viewed differently.
As in many Asian cultures it's quite normal to adopt various forms of non-confrontational behaviours.
Saving 'face' and Tampo is such a cultural behavior and does provide a socially acceptable way of expressing hurt feelings without actually resorting directly to either emotional or physical acts of hostility or resentment.
I learned years ago that once Tampo has taken effect there's not much that can be done.
On the positive side though, at least Tampo does have a cultural built in 'end-game'. Means it will end as suddenly and mysteriously as it began.
You'll soon learn strategies that help to reduce 'Tampo-time' by doing whatever you can to show some form of remorse. Be careful though, don't react too soon and don't leave it too long. Choose a good balance for timing.
Don't fall into the trap of treating 'Tampo time' as a good reason to nip down the pub for a swift pint. No no, she wants to see that you feel and show the pain of what ever it was that you did. (however inadvertently)
Also, don't try your own Tampo. That's going to be a real slap in her face and may only lead to who-knows-what escalations.
On the OP's question of what 'remained in your memory to these days?' I would say that Tampo when combined with the menstrual cycle may arguably be the most explosive combination known to man, and certainly one to be avoided at all costs. That's definitely

There are myriad of Filipina cultural anomolies to be shared and learnt.
I for one can't wait.
