is it necessary to know the story of both sides? why or why not?
Well that depends on you. What if magkaiba ang both stories on each side. Maaring ang truth for the other party is yung side nila, and that goes also for the other party, na yung truth nila is yung side nila. Siguro mainam if you're the judge, look on the bigger picture. Sino sa kanila ang tingin mo nagsuffer literally or sino yng naging mas madali ang situation? Sino mas nag benefit? Etc. Things like that pwede mo iconsider eh. It's not always the most convincing speech or acting eh. Look at how each one of them dealt with the issue on their own. What do they gain or lose from it? Ayun, something to ponder on. ✌️
Kung ikaw may kasalanan, ikaw magsorry malamang, kung both kayu at mahalaga siya sayo, ikaw na mauna magpakumbaba. If you want to save whats left of the both of you, ikaw ggawa ng paraan. Hnd uso pataasan ng pride kung tlgang mahalaga sayu yng other person.
