Steven is beside himself with excitement that he got a package addressed to him from Mickey Mouse full of stickers and stuff and a guidebook that he has already started reading. There's a letter in there from Mickey too saying how much he is looking forward to seeing Steven.
I have no idea who sorted this out. I don't recognise the handwriting, there's no return address, and the packaging gives nothing away. But whoever you are thank you from the bottom of my heart - you made his day.
