You enter the beis medrash on Shavuos night after your meal, dressed in your finest attire: a freshly pressed white shirt, your special Yom Tov suit, a new tie and cufflinks, shoes specially shined for the occasion. You greet your chavrusa, remove your hat and jacket, and sit down to learn. You are excited, even a bit nervous, as you look forward to an intense and exhilarating night. Despite your best efforts, your chavrusa detects your eagerness, and you, his.
