I come by plane

We have a very serious little girl aged 5 in our class. She doesnt smile much and seems quite mature for her age. We were looking at a 'chicken' poem today and putting actions to it. Anyway she very seriously looked at me and said

'I have seen lots of chickens hatch'
'Oh that's nice' 'Where have you seen them?'
'On my farm. I live on a farm'
'Oh I didn't know that, where is your farm? Do you come to school by car or do you walk?'
Girl looks at me straight in the eyes and said 'I come by plane' She nearly had me there, I believed all the farm story. What a sucker I am.
