There's a reason Calcutta has little to offer by means of 'hanging out' except restaurants & movie theaters. It's called 'adda culture'. Adda essentially means a bunch of people sitting somewhere smoking, drinking (if indoors), discussing politics or football and philosophizing. Bengalis aren't infamous for these without a reason! :)
Unfortunately the group of friends I have in Cal are big fans of 'adda'. Hanging out at home is their idea of entertainment. It's so not mine! A few months after moving to Cal, I got so sick of this I stopped being a part of it and would hang out only if we were going out. Well, mostly....
But now that my sister is back from the UK for good, I'm determined to reclaim my life :) Sounds dramatic, doesn't it? But for a person like me whose idea of a weekend/holidays is spending as much time out of the house as possible doing stuff - movies, lunch/dinner, shopping, coffee, whatever - it was nothing short of losing my life. With my sister back, life will come back to normal.
We enjoy the same things, my sister & I. And no, we don't get bored. It's the 'Sister Pact'! Good to have you back, honey :)
