Seeing the smile from your parent's face and hearing the word thank you that came out from their mouth.
When you allocate some of your salary and give it to them.
And I'm happy that I get the chance to do so.
I already allocate some of my salary to my parents (each), household expenses (water, electricity, foods etc), donation & my caretaker (the one who took care of me while my parents were working).
Hopefully I will be consistent/istiqamah in doing it and not to forget about it every month. Please remind me so.
