Go on and strike a pose for her or at her... the next time she
does that again and everytime she does that. See what happens next.

If she ignores you or get mad at you for following-up with her
daily routine, then it means that she doesn't like you. If she
upgrades her daily routine to scare the sh|t out of you again, then
you'll know you got yourself a fan. 
Alternatively, if you're really the shy and quiet type...you could
ignore her daily routine completely without a flinch for days and
weeks until she completely stops herself. Wait for two or three
days to confirm that she has stopped already and get her a card
instead. Tell her in the card that you misses her daily routine and
hope that everything is alright with her and so on (guy's crap
practically). She probably won't resume her daily routine after the
first card, so give her another card after two or three days again.
But this time, remember to ask her out...either for a meal, movie,
schoolwork, whatever excuses relevant. From then onwards, you're
the chaser. Well, do those stuffs only when you're serious about
her and do not attempt to use this to boost whatever male ego you
have.
Oh...one thing, it doesn't necessary means that you will succeed if
you really does all those stuffs. It's all up to you and yourself.

Good luck.
