Blocked, Abra decided. She was blocked, that had to be the answer. She’d meditated, worked with the police artist, tried active dreaming—which she wasn’t very good at—and still the time, effort and skill of the artist produced a sketch that could be nearly any man between thirty and forty.
Any man, she thought, studying her copy of the sketch yet again, with a thin face, long, somewhat shaggy medium brown hair and thin lips.
She couldn’t swear to the lips, if it came to that. Had they really been thin or had she projected thin lips because he’d struck her as such a tight-ass?
So much for her powers of observation, she decided in disgust, which she’d considered above average before this.
Of course, there wasn’t any proof her tight-assed, tonic-and-lime-drinking customer had anything to do with anything. But still.Nothing to be done about it, at least until after the holiday weekend.

As she filled out the description card, she imagined Eli’s family already on their way.2. what does "she'd considered above avreage before this"mean?3. what does "but still"mean?
