yes, you make a very good point!...
about the car; if we had a strange car in the driveway, i wouldn't think a thing about hubby telling me it's a friends, & i'm going to put new brake pads on it for them this weekend....
now if i walked in & he was painting the house, i'd be like
But, if my husband was accused of rape, or at the very least having an affair, I would know what kind of car the woman drove!
And I agree with the above poster that it depends on how they usually do things, but I don't know any men (i am sure someone would say their husband would, I just don't know any personally) that would choose a color. Unless they had already bought paint and selected a color, my husband would NEVER choose a color without my input because he wouldn't want to redo it when I didn't like it!!! Maybe he just used Kiltz or a base white type paint in preparation and that wouldn't look suspicious to her, but I still have my doubts about how she would not know....
