another point to think about: As the wife of an avreach who lives in EY we host sem girls all the time. they come over erev shabbos and from the minute they walk in the door don’t stop eating (except the anreix ones) till shabbos is over. don’t get me wrong I love having guests it’s a taste of home, but what are their parents paying for? so I have to scrap together money to buy a second loaf of fish? and than they want to use the phone, do laundry sometimes etc. . . these girls are thrown out of thier dorms all the time! not given the services their parents pay for.
I once asked girls from a really frum sem which hechsherim their were told to eat, they told me they which ones. I realized that these girls fathers would not approve of these hechsherim and I don’t belive that the principals of this sem would touch those hechshers with a ten foot pole. to earn a little extra money and buy their kids apartments in j-m they use all kinds of hechsherim for the girls. who supervises the kashrus in these palces? do you know who your daughter’s teachers are? which families they go to for shabbos? what hashkafas they are teaching you daughters. I have heard some crazy things from girls over the years. (usually the same things from the same sem every year)
