Heng/Suai?

sometimes when something happens and then u start to tell urself "wah heng ar" or "damn suai leh", think again. was the situation reli heng or suai. contradictions do accur. for example, u walk down a flight of stairs and slip, then u managed to grab the railing b4 u land on ur butt. izit heng tt u grabbed the railing? or izit suai tt u slipped?

- u lost ur bag containing everything u have at somewhere far from home in the middle of the nite, but u found $10 to take a cab home.
- u get drenched in the rain with no shelter arnd, just when u are abt to give up running a cab appears.
- a dog chases u n u start running, a flowerpot dropped from above and landed behind u a few feet away, u got bitten by the dog eventually

HENG OR SUAI?? if u say both, how can tt be correct if 2 opposites combine
