How do you know for sure that you haven’t lost all those pregnancy fats?

Simple. When someone offers you a seat in the MRT!
Yes, that was what happened to me a few hours ago.

I stared blankly with a puzzled look when her gestured at the empty seat.

Kind lady: “Opps sorry… I wasn’t sure and I couldn’t tell.”

Me (smiling outside, cursing inside): “It is okay, actually I have just given birth.”

Kind lady: “Oh I see, maybe you should still sit then.”

Me (laughing): “In fact, all the more I should stand to burn away those fats! Thanks anyway :)”

And boy was I glad that the next stop was mine.
