When I was 10, I unwrapped the present, removed the present, and rewrapped the package and hid it back under the tree.
Yes, HONESTLY
My plan was to return the present to the empty box just in time to unwrap it (again) on Christmas morning.
Got caught.... something to do with a noticeably empty box being found when the presents were being rearranged under the tree.
Just wondering... what would happen if you tried the same trick?
