There is no such a thing is as a Bangla thing. Bangla is inside you, and if you do whatever you are good at with enough gusto while images of Tigers and your flag floating about in your head, than you are doing the right thing!
Remember, culture will change, pride will not.
Btw, this forum itself is a fantastic outlet for Bengali Pride, not just cricket. So everyone pat yourselves in the back for making it what it is.
His excellency, Shere Bangla, descendent of Tipu Sultan, the Uniter of the Two Bengals, the Wily Bengali, the prince of all things cool, I present you Roey Haque the 1st.
