This question is solely academic and has not come up with my DS: once a candidate accepts his appointment, what are the consequences if he changes his mind before I-Day (besides feeling really embarrassed)? My DS will be receiving his appointment in the mail soon, and a while ago he said he'd sit on it for a few weeks despite being 100% positive about going. He thinks it's a more mature approach, that showing some restraint in accepting indicates that he's taking the commitment seriously. I'd like to be able to tell him to turn it in as early as he wants, and if he has an epiphany in March that he's meant to go to seminary or something, then the consequence is x, y and z. (BTW, my money says once he gets that packet in the mail, he turns it around within a week ).
