My mil is a Professional in a different career besides being a shadchan. She is an extremely busy women, and still listen to all the crank calls.
The recent most upsetting shidduch that she made was; girls parents promised 10,000.00 if she got her engaged. This girl had massive problems. She worked days to get this girl engaged, when she finally did the Girls parents paid her 2000.00. And its not like they dont have money, these people are loaded. My Mil was very upset about it. Dont promise if you dont feel like paying. End story is they ended up getting divorced boy and girl had to many problems to live together. Dear mil still feels guilty about it.
