MUM-LHR-MUM

So, I was just lazing on the couch, flipping around with a zippo and leafing through FB pages, when my partner asked this rather humble, but indescribably deep question: 'Your heart isn't here [London], right? You want to be in B'bay...that's where your heart is...'
My first reaction was: I wish even I knew where my heart belonged.
Will my heart, actually ever belong to a particular city, location, destination?
I grew up and so far spent the better half of my life in Kolkata, literally 'grew up' in Pune, matured in Mumbai, learnt and experienced in London...and now back to same old B'bay. The question is, this time around how much more mature will the 'city of dreams' make me?
Growing up, indeed, am sure will continue in B'bay...but is that where my heart truly belongs, then? I wish I knew. But until then, probably it's my next, but not last stop. It's only a stopover.
And the day I figure what I want/desire as my city, my destination, I will not be the same nomadic soul...
