There's another situation:
You get on the bus, there's 1 auntie in front of you, but she
walk so slowly to the seat and given the fact that you're behind
her, you have to walk slowly too, then the bus started moving and
she immediately grap the nearest seat and sit down and leave you
jerking around with the moving bus, is that consider to be
inconsiderate? or is she simply ignorant?
this one is ignorant. she is living in a "me" world.
