I'll be honest. As our wins have to started to become more frequent than the not so distant past, the excitement level during the occasions of wins has started to vary. Now our expression of celebrations do depend on the context a lot (for example - the first two ODI wins against WI); and it's nothing unusual, it's normal. The more you get used to something, the less you would start to be surprised by it.
However, our passion for cricket deep within, I believe, will would stay the same for a very long time, the sole reason of which being the fact that that's the only thing we're current any good at.
