Why don't i get starstruck?

i LOVE lady gaga, and i was pretty excited because i was
going to her concert. when i got there and saw her. i wasn't going
crazy like everyone else.
idk why. mabye cuz i was kinda embarrased of going crazy. i also seen
celebs from soaps at amusment parks and got there autographs. am i
probably those people who get nervous by celebs and just like whatever
but excited. becuase i have friends that freaky out. but i don't get
like that.?

any similarities?
