Anytime a woman tells you that "we need to do something," that usually translates into you need to do something that she wants done. If you happen to have a mouse in your pocket, it could be construed as "we" need to do something. Otherwise it's just another "honey do" list that she is trying to make you feel better about by acting like she is including herself on the action part of the work when she really has no intentions of doing anything but riding you like a bad claiming horse until you complete what she wants done.
