A2 is a sneaky one

A2 is almost 4 now and he is showing quite a sneaky side.
V spotted an apple core near the staircase and asked A2 who left it there.
A2 responds "A1 was eating an apple"
V asks again "Ok, but who left the core here"
A2 says "That would be me"

A2 was playing with a car that I hadn't seen earlier and I asked him where he got it from.
He says 'Miss S gave it to me for doing good job"
I am a little suspicious. Montessori schools don't give out cars as rewards.
Later in the evening I ask him "If I call Miss S and ask her if she gave you the car will she say that is correct?"
I get an hesitant 'Maybe"
"Well, where did you get from"
"I brought it home from the YMCA"
"Uh Oh"
