The Clicking of a Pen

She is my student. She sits to my right and one seat down on the small table. When she speaks, she clicks her pen furiously, in time with her snappy syllables and her oddly-spoken vowels. I grind my teeth, hearing not the sentence she's trying to say but "Iclickthinkclickclickthatclick thisclickisclickaclickveryclickinterestingclickclickclickclass." I reach over and touch her hand briefly to still the echoing clatter created by this tiny, tiny torture device.
