Wisdom beyond their years

Overhead in the pedestrian street outside my house - three little girls (about 7 or 8-years-old) were playing with their bicycles, and chasing each other up and down.

"Now, you be posh totty, I'll be an emo, and you can be a charver...."

Which begs the question, how exactly does one ride a bicycle if one is posh totty?

Leaving aside such complications, it's nice to see that aspirations in Gateshead are as high as usual...
