A student who had spent the day learning in our yeshiva in Israel returned to his old yeshiva in a nearby city, saying that he'd think over the possibility of transferring to ours. His decision was in the affirmative, and after about a week he arrived to begin his studies with us. The first morning did not look very promising, however, when he appeared about two hours late for the morning session. From this it seemed that he was sorely lacking in the motivation and discipline necessary to succeed in the formidable challenge of learning Talmud. I was already mentally assigning him to the ranks of the well-meaning but under-motivated, when I heard someone say that our new friend was still suffering from jet lag after returning from the States. It seems that the week's delay in transferring to us was due to a quick trip home. So it was not laziness, but travel fatigue that caused his lateness. Fortunately, I now had the opportunity to revise my overly hasty assessment of this new student, and to give him the fair chance he deserved.
