Instruction for Sneaking Out of The House

Sneaking out of the house ......toys that is.....is apparently a hot topic in PreK. Grayson always sticks a few toys in his backpack to play with in after school care. The latest hot toys in his little mind are BeyBlades and apparently his little friend Ricky happens to have some.
Now I may or may not have mentioned before that Grayson is quite the scammer. I wonder after hearing this story tonight how long he has been working on getting his classmate involved in an effort to get his hands on some BeyBlades. (Grayson doesn't have any but they are on every list for times he could possibly get a gift this year) Dad asked Grayson today if he got to play with BeyBlades at school today and he was told "No, Ricky's dad caught him sneaking them to school so we didn't get to play".
As I am hearing this story, Grayson is sitting in the bath telling us how Ricky needed to change his tactics (tiptoe and be more quiet) in order to sneak his toys to school. In the back of my mind I am hearing my sneaky child (who generally tells us he is being sneaky so it defeats his efforts) planning this attempt with his friend. Perhaps I need to start being more aware of him helping others be sneaky in an effort to benefit himself since he is unable to sneak off to the store to purchase what he wants.
Once again I feel that I have been let down by our parents who neglected to tell us that four year olds are practicing their pre-teen skills and this is our chance to start figuring out how to work the system in our favor. I am a little nervous about the future seeing as it takes significant energy to keep up with the current schemes.
