Rinoa's index finger.

[Dark Matter]

Every time I see someone do something similar I get a wave of nostalgia, and it really touches me.

Yeah!!!
I got a chance to raise my finger just like Rinoa when I won the Run (half marathon) last year. Then, I bought my PS2!!!
*sigh* That's the last chapter in my story.

For me, it means "It's for you". ("It" refers to the shooting star, of course.)
Sometimes, Hicham El Guerrouj'll do the same too.
He's the King of Mile.

It's always been my dream for a beautiful girl to raise her index finger at me from across a busy party, walk to me and say "You're the best looking guy here."

WHOA!!!!! You can read my mind!!!!!!
