My niece (3.5) was watching a movie up the sofa with my Sister and BIL (Frozen or similar) when she suddenly started staring into a corner and started to say "ssshhh it's ok" over and over.
My BIL asked who she was talking to and she replied "the little boy in the corner"
My sister (entertaining her more than anything) asked "aww why is he crying?"
Niece: "he's hungry"
Sister: "oh right, what does he want to eat?"
Niece: (very casually) "us"
She is a complete wind up merchant now too but my BIL is still horrified by this moment!
