infielddad and swampboy,
let's assume the job hypothetical is different (which I do not agree with). You both agree that going back on your word is acceptable in that situation?
BTW, swampboy, I agree it is an unrealistic scenario (dream school), but it is made to prove a point to those who would advise their son to stay committed no matter what. There are always exceptions. However, I think that is the only situation in which I would advise my son to decommit.
