Approached for the first time yesterday. College girl behind me in line for bus. I said 'Hi', got a hello back, I left the line and disappeared. Went under the bus shelter since it was raining lightly (or perhaps I'm rationalizing here). Till the bus arrived, the queue was huge. Found her, said 'Let me come' and jumped the queue.

I wonder whether I should've chatted her up instead of disappearing? Also what should be my next move? This girl's in my class.
