2 people standing right in front of u.
An old man, bent over, looking so weak and fragile, trembling on his legs and holding onto his cane with more strength den a baby would need to suckle milk and it seems that if he trips, his heart will stop and die immediately.
A pregnant lady, thin and petite in size, with her future generation. And her womb so swelled up that u swear she's in her final trimester and if she just jiggles a little, u swear the baby is gonna drop right out between her legs or if the train jerks and she trips, u swear she's going to miscarry immediately.
And unfortunately, it seems that the ppl around you are absolutely oblivious to the both of them and all are ignoring this old chap (who seems he's gonna croak any minute) and this very pregnant lady (who seems she's gonna have her baby any minute).
Who would u give your seat to?
