Who Can It Really Be&;#063;

What is it?
Surely not, a Police box!
Out steps the young Edwardian man,
Or so he seems.
With a companion in tow,
Up they walk to me.
The man offers me a jelly-baby,
I accept, kindly
Then off this strange man walks:
But the companion stays awhile.
Then off she goes too!

I later discovered who they were,
A pair of time travellers
Called the Doctor and Izzy!
