Another question I have: what about requirements? (this has come up in my own relationship) Suppose the two partners have different ideas of what constitutes "cleaning the house". One might think that mopping and wiping dust off furniture is necessary, while the other might think vacuuming does it. In a real situation, the two contractors don't just compete on price but on product. But in this case product never enters, unless there's a careful discussion up front about exactly what the requirements of the job are. This doesn't really sound like it would decrease stress to me.
