That is the question on the lips of every four year old. Well, at least mine. I recall wondering a year or so ago if we were in the 'why' stage. I can now say, with certainty, that when your child is in the 'why' stage you WILL know!
'Mama, why do policemen carry little guns?' (As opposed to Daddy's big hunting guns I suppose)
'I don't know Hunter, why do you think?'
'To shoot little bad guys?'
'I think thats probably why'
The 'why' questions continue all day long, particularly while we're driving.
'Mama, why are you stopping?'
'Because the light is red.'
'Why is the light red?'
'So the other cars get a turn to go across the road'
'If you don't stop will the policeman get you?'
'Yes, and he has before and it cost us $150.'
'Why does it cost money to not stop at the light?'
'Because the law says to stop.'
'Why is there a law?'
Its aggravating but its also very entertaining and I love seeing the little wheels in his head turning.
