Glances
It was her eyes that gave her away, she'd learned that some time ago, and she still couldn't stop giving herself away when he was around.
She'd glance at him from the corner of her eye, a quick flit just to see where he was in the room without looking like she was interested. After a few minutes she'd grow curious and glance again but this time a little longer before catching herself and turning away, all the while wondering if he had noticed. A little longer still and she'd look again only to find that he had noticed and was now watching her with interest.
Then she'd frown and turn away, the mask concealing the redness in her cheeks but not the tiny upturn in her lips at the thought that he was watching her too.
