When I was in fifth grade, I switched schools. Someone there asked if I had been born in the UK, because I had a trace of the Queen's English in my speech. I assure you it was not affected by me, but a natural byproduct of being raised in a home where the only thing on television was PBS, then recycled British children's shows via 1985 Nickelodeon. The Third Eye, anyone? How about The Tomorrow People? The strongest, quickest and best, Dangermouse. And of course Doctor Who!
Thanks to the wonder of the internet I can continue this tradition with my kids. They are Whovians through and through, and Gilbert and Bede currently love Alphablocks, a CBeebies programme. Enjoy!
