AIBU to lie to my DS?

[AmazingBouncingFerret]

I told him there was no cake mixture left over for him to eat.
He goes off to his room to play whilst the cakes are cooking.
I sneakily eat the cake mixture out of the bowl and very nice it was too!
It's my cake mixture. How dare he want it.

Just don't get caught.

Having a high shelf is no good when you have teenagers.

Having a high shelf is no good anyway. DS is 3 1/2 and will be taller than me soon!
