Cleaning your house enough to get it to a level where it doesn’t look like you cleaned just for company. Minimal effort (depending on your base level of slovenliness and/or how many children/pets you have), you don’t appear to be the slob you really are, and your company appreciates that you ‘kept it casual’ for them indicating a level of intimacy that may or may not actually exist, but fake it till you make it, right?
