The 6-year-old son of my vicar in Fulham is a bit of a transport
whizzkid (he's learnt to read by memorising the entire Underground
map!) and is well on the way to memorsing the entire London bus map.

He was recently asked to write about a family trip at the weekend. His
sentence "we took the Overground from Kew" was wrongly corrected by
his teacher to "Underground"!

Silly teacher!
