Your three responses obviously come from bias and over opinionated -ness (can’t think of an alternative word) that shows up often with this topic. I sure hope no girl ever misses out on what could be a very valuable experience for her because of armchair complainers who don’t mind generalizing their personal opinions as if they belong to everyone.
OP- you probably have a good idea about whether or not your daughter will benefit. If she isn’t a rule follower, if she is a risk taker, if she rarely comes home before midnight, if you don’t usually know where she is at any given moment,if she tells you why she wants to go to seminary and non of her reasons sound like healthy productive ones then maybe a year in another country isn’t the place for her. Unless of course you find the right place, in which case it will be the best place of all.
