Hi

I am a desi guy in australia. At my workplace is this gorgeous but shy local girl whom i talk to on regular basis and most of our talk is on issues related to work. Last week she asked me "What are u doin tommorow(Sunday)". I have observed that she is more open when she talks to other guys, but goes blank and red while talkin to me(Just like me, actually!). Could it be that she is interested in me or it's just because of cultural differences she is shy?
I was thinkin of asking her out for a movie or dinner next time we meet.
Shall i do it or wait for sometime or never do it?

THANKS
