Vanessa raised her eyebrow at the man who asked to dance, but made no reply otherwise.  She gave a friendly wave to Cath, but didn't help herself to a beverage.  She wasn't thirsty, she wanted to wander.  She hated being still.  Her feet took her in ever increasing circles, her eyes scanning the crowd more out of boredom than any expectation of finding something.  Only when she reached the edge of the crowd did she stop to glance around for a good vantage point, somewhere she could watch the entire crowd from.
