when we were talking alone she drew a heart on her paper twice. she sort of did it subconsciously, possibly as a nervous habit, but i noticed it and she knows that i did. she did this another time too when we were alone talking. we call each other "husband and wife" playfully. another girl who liked me would always draw a heart on her hand without even realizing it when we talked on the phone, so this is why it means something to me.
