Inconsiderate commuter

Few years back, My friend who got baby face (she looked like she’s in early 20s, however she’s in her late 20s and her clothing style also looks like uni student) was pregnant and sitting in mrt reserved seat. Her baby bump isn’t really showing, and there’s another pregnant lady standing in front of her waiting for her to give up her seat. She din asked or say anything but literally bumping and pressing her with her big pregnant belly. What annoyed me more is when the mrt got a bit bumpy, she deliberately press her belly against my friend’s face. My friend was so annoyed that she decided to stay still and not telling her that she was pregnant as well. To make things worse, another passenger get up at the next stop, the seat was empty but this pregnant lady does not want to seat on the empty seat and still aiming at the reserve seat. I was like.. wth.. If only they communicate then this weird situation could be avoided. For her next mrt ride, to avoid being victimised, my friend wore the pregnancy sticker so she could tell ppl that she’s pregnant, however some ppl still din give up their seat for her (probably they thought that the sticker was fake...) Moral of the story: life is not easy also when your baby bump is not showing.
