I just reread the young lady’s post. I never believed in having a young lady meet the boy’s parents up front. I find it too nerve-wracking for a young woman and a grueling situation which is totally unnecessary until you know if the dating process is going anywhere. Since the boys usually have the upper hand in this game, it is even more hurtful when a girl goes to the trouble of meeting the boy and his parents and then gets dumped.
A young man in the dating parsha, should be mature enough to go on his first date alone, with out shomrim. If he cannot stand up to his parents and say “no” and cannot stand up to his parents and say “you are not going to embarrass me by……” then he is not mature enough to date.
I actually thought that the prospective mother-in-law was going to ask for the handwriting sample from the shadchan before the kids went out. Although I think the whole idea is ridiculous, that would have been the least humiliating way to do it.
