Some guy brought his mom to UVA Admitted Students Weekend in 2006 (maybe 2005?) and during one of the panel discussions, Mom raised her hand and was dissatisfied with campus meal options.
She said something like, "This will be the first time he's lived away from home. How is he supposed to eat???" Apparently the admissions panel just sort of mumbled through something, and all of his classmates sat there in shock. Then they all ran home and posted about him on the LSD pre-law board.
Well, one of the things that law school are ranked on is the rate of students who attend after being admitted. If they have reason to believe that you won't be attending again, then you may be less likely to be admitted.
Most law schools have a process where you actually "defer" admission that doesn't require you to reapply next year. Usually you must put down the nonrefundable deposit, however. Some schools will allow most students to defer, but some require that you have extenuating circumstances or a compelling reason to defer. Check in with the admissions office about the process of deferring admission.
