Dont worry Tupac, youre not alone.
If you have studyed German, you know there are two types of "you": du and Sie. We got the same stuff in hungarian.
Three weeks ago i was holding a camp for a folk dance group, as a musician. At the first dinner, a 17 y.o. pretty girl came to me with a trayful of cookie and asked: Wünchen Sie...? I asked her, what she thought, how old i am, why she said "Sie" instead of "du"? She said, 35... just guess my melt down face, im 21 dangit... and i was freshly shaved that evening, no bristle or anything.
When this happens, you know that you are getting older.
