You know you're a cosplayer when...
No matter where you are or what you are doing you'll see something that is "perfect for [insert character]" even if you have no intention of ever making that costume.
For example: You're in a pet store and see the aquarium air filter tubing and think you could convert that into part of a costume or you are in a kitchen supply store and think if you take apart the garlic press you could use it as part of a prop. Or perhaps in the automotive department and thought you could use a hubcap for a shield or armor. So many stores, so many possible cosplay supplies...
