one of the biggest compliments and chessed you can do for this guy is to set him up with someone else. most people who redt shidduchim vaguely know the two parties. if you know both sides pretty well and you tihnk he is more for your friend then you are helping the shidduch crisis. your friend will see that you think this guy is good enough to go out with her and he’s not some creep that you went out with that you want to forget about.
kol hakovod! and hatzlacha!
