Hmmm. EgyptianCat, I don't remember agreeing to read anyone a bedtime story, but I like reading stories, so I'm happy to oblige!

How about Rupert the Bear? He's all white, (hooray!) and he used to be my favourite when I was a little girl.
Spongy, make sure you don't let TenPencePiece steal that trophy back!
TEGH - what can I say!
I am flattered and honoured to see my name now features in your sig - even though I'm aware it was possibly meant as sarcasm, though it's hard to tell!
For your siggie to be ENTIRELY all_white-friendly, the space between "white" and "friendly" should be hyphenated, as I have just hyphenated it, because it is a compound adjective. However, I'm aware no one else cares, or even knows what a compound adjective is, so feel free to leave it as it is.
Things like that
hurt when you're into punctuation. It makes me wince to read them, but such is life. We can't all be good at the same things. Case in point: I don't know how to crochet.

I don't mind. I just want a bed time story

And you did say it, you said it just 15 minutes ago. Do you not remember all_white?
