Magic

I found a suitcase in an old storage room. I opened the suitcase and found a magician inside. He gave me a box of beautiful magic. I thanked him and closed the suitcase.
But this doesn’t make sense, I said to myself. I opened the suitcase again and as I expected, no one was inside. I was only imagining things.
 
Nevertheless, the box of magic I received was true. That I could never figure out.
