Met with a couple of friends and their two young children for lunch today. This was the first time I've seen them since transitioning. Anyway, their son - D# - is about six years old and a mad keen Doctor Who fan. Before meeting up, so they tell me, they tried to explain to him I was now Grace...
Them: So Grace was a woman stuck in a man's body, but now she's a grown up and can be in the body she wants to be.
D#: So she's regenerated...
(Then ensued a long conversation about how the next Dr Who should be a woman.)
Too darn cute!

Funny thing is I've also been thinking of my transition a bit like a regeneration too...
