I know that feeling. The Target thing. Wal-Mart wears me out. You reminded me of myself and H when you said you used to say "You owe me one" . We did the same thing ourselves, mostly with rock concerts. I went to Metallica for him. He went to Michael Bolton ( back in the day) for me. That kind of thing. Perhaps you should re-initiate that kind of thing.
Little things like that can have deep meaning. My H used to always go grocery shopping with me, and at the check out, we would both guess how much it would be. Whoever was closest without going over got to choose the "activity" that night, if you catch my drift.
