ha ha! guess what?
i had that experience before. i once know a girl who behaved juz
like this, always very tensed when she's talking to me, shorter
speeches than when speaking to other friends in the group, evading
looking at me in my eyes, always look down.
but i never show any extra concern for her at all, not even
platonic concern like u did.
and when i noticed that, i stop talking to her when we were out in
a group, completely dont talk to her.
then one day she called me on the phone, i can recognise her caller
id, but she never talk. i hello hello still no reply. then she
hanged up. i still dunno what's wrong, but i dont give a damn. i
remembered i continued playing my playstation and didnt bother to
find out why. then abt 2 hrs later (i was still playing), one of
our common friend called. he told me that the girl called him and
cried on the phone. i still blur, asked him what happened.
and he said that she actually had a crush on me. i went "huh?".
never expect this at all... so that explained why she behaved so
tense towards me.
