But there is no switch.

'Tadaa! HarHAR! I'm back!' I'll shout to my roomate, Cecilia, the moment I fling open the door of my hostel room.
I smiled, even upon making eye contacts with strangers, female strangers, mind u.
And so, I find myself happy these days, happier than the usual happy me.

It's always rewarding, to realise that people whom one cared for, cared the same in return.
But many a times, one will devote one's heart to people who seems to win that special attention from one, effortlessly.
At that point, one no longer judges the action of that special someone, neither do one raise the issue of equivalent exchange as it no longer deals with one's calculative mind, but one's emotional heart instead.

On or off?
The problem is, there is no switch.
Let time tell. (;
