Over time, Kai-May and Ray's satisfaction will decline more than Veena and Jerry's will as Veena and Jerry’s interjection of humor into their discussions most likely makes them a lot happier than Kai-May and Ray since Kai-May and Ray are seriously focused on the problems themselves which leads to a boring discourse. They also forget to take a break during their discussions by having light-hearted talks in between, which diffuses a lot tension.
