sounds familiar. Once a week, think if this is always once a
week, you should be able to pluck up your courage to "chiong" to
approach her !!! Do you notice if she still shy away from you. IF a
gal is shy in your presence, you may stand a chance, as it may
indicate she is also interested in you. I will be shy in the
presence of the guy I like, too!
If she smiles at you and you gauge that she is in good mood, then
you can smile at her as you usually do and just say "hi". If she
takes this well, then next time you can smile, say "hi" and ask a
very short open ended question.
