Some everyday carry around items for me include carebears, light bulbs, snowglobes, dog biscuits, popcorn kernels, tape, ketchup, empty salt shakers, air freshners, a Dasani waterbottle filled with Purrell Hand Sanitizer (can't get enoough), and barbies.
But in all seriousness sometimes when people ask me to show them a trick and I pull out cards they are like "What?", "Why do you have cards?", "Really like magic don't you?", "Always prepared?", etc.
