IŽll tell you what you should do enter your classroom pass by her and say "GOOD MORNING!" (not very loud of course) if she anwers then you just leave it at that but if she doesnŽt...you say:

"I said good morning!" (but in a calm and funny way) know she is simply rude or too embarrased if she doesnŽt answer.

The next day you do the same thing and eventually (two to three weeks) you will start to talk more even if she doesnŽt want to date you, you can show her what a cool and funny guy you are and she might start to like you...or not it depends.
