"It's Okay"

Today is the 3rd time I am being offered a seat on the MRT, yet I told the person "It's Okay".

I am actually happy to know that there are considerate Singaporeans around who volunteer to offer their seats for pregnant woman, thou' I have heard and seen many horrible encounters. So I am glad that till now, I've been offered the seat on 3 separate occasions. I always decline the nice offer, thinking that:

1. I am getting off at either the next stop/ next 2 stops
2. I am basically not that BIG and HEAVY now
   
3. I am not tired at that moment
4. I feel its a hassle to try to swop positions with the person who offering the seat to me.

Well..I am thinking if this nice act towards me will stop in the future when I really and badly need the offer.

Hope not.
