I've got a few.
When you sit by the beach and wonder whether you should go into the irradiated water
When you are oh so glad when you have a bottle filled with clean water with you (guilty)
When you are wondering why is the Nuka word missing on the bottle of coke.
When you don't walk closer than 15 meters to parked cars.
When you wonder why you didn't get the AK at the gun store instead of the .22 (guilty)
When you wonder if you can fix that leaky pipe with random scrap metal you see outside
When you really wish you had some power armor to help you carry groceries (guilty)
When you vacuum the carpet and wonder if you can modify the thing to shoot teddy bears
When you try to combine a lawnmower blade, a gas tank and a hand brake to make a flaming sword
(No, I'm not THAT obsessed. Yet.)
