"I can open the Lowes store with this key, so I don't want to lose it."

While decorating the house for Christmas this year, I noticed that Wil was doing everything with his right hand because he had something clutched in his left hand. Annoyed that I was getting only half of his help, I demanded, "What is so important that you can't put it down for five minutes and use two hands?"  He took me to the side and gently unfolded his hand to reveal what looked like an average silver key. It had the Lowes logo across the top since that was where it was made and I recognized it to be one of our spare house keys. Realizing that it clearly meant more to him, I asked, "What's so special about this key? What does it open?" He answered, "I can open Lowes stores across the country with this key, so I don't want to lose it."
