My ears perk up when someone talks about a new dish they had for dinner, or an old favorite. I listen closely, and often even jot down the instructions. But quite honestly, I rarely cook anymore. Maybe once a week, twice if I'm really on a roll, and then its usually an old no-brainer standard. Tacos, maybe a crockpot stew.
I think I pay attention to those food ideas as a connection to those days when I had family at home to feed. Now, cooking is actually almost a chore to get through. There's a lot to be said for frozen entrees!
