Bagpuss's best friend

I have a friend who has got himself one of those 'electronic
girlfriend's and I recently found out that she's called Milly.

Now I didn't know if this was a doll, an Internet kind of thing, a
Tamagotchi or something in the dark web that might be a little bit
more.. well niche, shall we say? Or maybe something even more
high-tech, something virtual. A Fembot perhaps. After all, I have a
robot that does my hoovering - that's already more than most women
will do nowadays.
Basically I didn't know what an electronic girlfriend was.

Then I realised there was no such thing.

She's just called eMily.
