britney_chengx,
I think if you have so many reasons not to give away seat to that woman (especially you are pregnant, you are the one in need actually), you should refuse to offer her the seat. You may tell her to ask other men politely. Why would you give your seat to her which made yourself so angry?
I don't understand why so many people ask women to give away seats because I think that it should be men who give away their seats to the one in need. Gentleman manner. Also, women feel dizzy more often than men.
If you think that 個肚大左...一出街 都唔知d人望乜...就好似要睇穿你個肚咁 and you want to 同d望住你個肚既人講:望咩啊. Just say it lor, what are you afraid of? 大肚婆大晒架. Don't make yourself mad when you are pregnant.
I also had many bad experience that made me angry. I'd travelled MTR and deliberately went to the end of the MTR train (head / tail) in order to avoid the crowd. I'd 2 times' experience that a 麻甩佬 at his mid 40-50s that they took my seat. I'm sure that they knew that I'm pregnant as my belly was big and I was already in 7 months' pregnancy stage.
It really irritated me. One even closed his eyes in a second pretending not seeing me.
I had also another bad experience that no one pressed the "open" button when they're inside the lift. When I was walking inside the lift, the door has been closed. My belly had been "trapped" by the door. It made me feel extremely upset. I really wanted to "DAXX" these uncivilized people. They're really inhuman and impolite.
