go on a date with my wife once a week

Saturday, our kid will be with his real Dad, so I called up my wife at work, and asked for “that cute receptionist” (they know my voice pretty well when I call). Then I asked her if she wanted to go on a date with me this Saturday, and she said yes. Now I got to plan it! I’d like to do something out of the ordinary, but am kind of limited because she’s pregnant and cannot handle a whole lot of activity.
