Just tell the wrose that could happen is you never speek to her again
I hate to be unhelpful, but this just isn't true anymore. In today's society there are so many new ways to ruin somebody's life. Facebook, for example.
The safest option is to quietly introduce yourself, and hey, want to go get some coffee sometime? I combined that with waiting for the end of the school year so it wouldn't be a big thing and wouldn't follow me through high school if I got rejected.
I did get rejected, but I have no regrets, and would have come across much worse and creepily suddenly "confessing my feelings in a burst of hope and confessioning" (which I was seriously considering).
I think that she'll understand unless you make yourself sound like a stalker. Bursts of passion work great in movies, but in life they're just begging for a restraining order.
Also, go for a neutral activity that can be interpreted as just being a cool friend. Then, after food (food is important!) ask, after the two of you know each other well and you're sure you want her to be more than just a friend. If she asks first, DEFINITE plus.
You're doing a good job of being patient so far, don't ruin it by scaring her with a sudden feeling exposure when she doesn't really know you.
Hope this helps!
