Busted

I've been outed. Ever since LL was born we've tried to give him an exemplary diet and lifestyle. So, I usually wait until LL's gone to bed before breaking out the junk food. Last week while Ann was at work and I was putting LL to sleep:

Me: Goodnight LL, have a good sleep, try and keep your diaper dry.
LL: OK.
(pause)
LL: Daddy?
Me: Yes?
LL: Where are you going?
Me: I'm going to my office to do some work.
LL: OK.
(pause)
Daddy?
Me: Yes?
LL: You're going to the office?
Me: Yes, I'll be right here in the next room.
LL: OK, but don't go (LL is now making krinkling noises followed by the munching sound of chips).
