Why oh Why

During tv time, curious Ivan shoots me non-stop with his questions..

[Ivan] : Mummy why the policeman didn't wear cap?

[me] : Because he doesn't want to?

[Ivan] : Why he didn't wear cap?

[me] : I don't know

[Ivan] : Why the policeman didn't wear cap?

[me] : Why don't you ask him? I don't know

[Ivan] : Why he didn't wear cap?

[me] : I don't knowwwwwwww

[Ivan] : Why he didn't wear cap?

[me] ...........................................

No wonder they say 3 years old are full of Whys. I didn't believe them last time because Ivan started with What? How?

Am so wounded by Ivan's M-16. *uuuuurrrrgghhhh*
