My Math Forum Interpretation of Limiting Distribution

Let $X_{(n)}=MAX{(X_1,...,X_2)}$. Define $W_n=n(1-X_{(n)})$. Find the limiting distribution of $W_n$ as $n$ increases without bound. Can you identify this limiting distribution? Give an interpretation of the result obtained above. So, I managed to find that the limiting distribution follows an exponential distribution with mean 1. However, I'm not quite sure how to "interpret" this. What's so special about $W_n$ that makes this result significant when $n$ grows large?
