Nope. Strike up a friendship. Appear non-threatening. Then one day, as you would approach her for conversation, do it, and then just plunk down beside her and continue stretching, as though it was just a nothing, little, friendly gesture. Works every time. Carry on in a normal tone. Don't flip out. She'll be surprised, but it will be your reaction that will set the tone. If you appear indifferent, then she'll take it as such. If you appear wound-up, then she'll pick up on that. Good luck.
