our girl leans back a little in her seat, gives a little nod to her friend seated across the lecture hall. types a reply. she puts a foot up into the sink, testing it to see if it can take her weight. then climbs up and straightens on wobbly legs, until her face is near the filthy dust-clogged vent. suddenly his eyes go wide as something lurking under the seats seizes his hand and jerks him in hard. she reaches under to scoop up some of the yellow snow. retrieves it so she can hold it under her nose and sniff. she closes her cellphone.
