How is it not right? Google is correct most of the time. But it is good for looking up definitions and etc etc. but, how is it "Not right"?

And I didn't use google b/c sometimes, Google ain't right.

Oh... Thx u. So I feel Nostalgia when I play Halo: Reach, then...

There is Google, my friend. But, nos·tal·gia näˈstaljə,nəˈstaljə/ noun a sentimental longing or wistful affection for the past, typically for a period or place with happy personal associations.

I DONT GET IT!! WHAT DOES " NOSTALGIA " MEAN??!! "
