Dolly is my (almost) constant companion in SecondLife. Her backstory is that She has been with me since I was 1 year old, when she was created by my mother from an old nappie [that's diaper for you uncouth USians] <- sorry, Dolly seems to have learned HTML [like it's hard? I can do MordorScript, Cthulu Calls and Microsoft EULAs too if you like].
In RL Dolly is based on a similar rag doll I did have from around age 1 created by my mother from an old nappie. However the RL Dolly had a name other than "Dolly" and was not able to speak for herself, or play nasty tricks on people who insulted her: if dolly disappears from my left hand, BEWARE! (In fact, even remaining in my left hand she can be pretty vile).
SL Dolly is sometimes my friend, but at other times she enjoys slagging me off in front of (and along with) my other friends. She tells lies about me and generally mis-behaves. Don't take ANYTHING she says to heart, she changes her opinions of people and things like the wind and will say something outrageous for effect as often as out of conviction.
I am pretty-well stuck with Dolly. Attempts to dispose of her have resulted in unpleasantness that has needed deep repression. I did once loose her in the assets-server for a day, but even that didn't hold her for long. For all her shenanigans, I think I would miss Dolly if I ever really lost her. [My nefarious plan is working!! - Love, Dolly].
[BTW, LaeMi can only hear (or read) what I say if I want her to - a very useful ability. Mwi-hi-hi-hi! (you try laughing manically with a pint-sized body!)]
Dolly is really a self-built scripted object with a horrible spaghetti-code of scavenged and origional scripts linked through a very long if...else-if chain on private chat intercept. I am not sure even I know all her capabilities anymore. She might even become truely sentient one day. [She might just... one day... yeah one day!]
"Why does almost every sit-pose in this universe end with me down your knickers?"
"So are all the SLers who go around as demons and monsters going to show up for Haloween in boy/girl-next-door AVs?"
"Bite me! ... NO! that is bringing back very unpleasant memories of LaeMi teething."
"I was in a dark, bad place... Why did you disturb me?"
"Ooh! Ooh! Someone's companion creature is using channel 666 without an owner-listen filter! Mwi-hi-hi-hi! Let's have some fun!" [I can also speak to LaeMi alone.] ("also" Dolly? "also" in relation to what previous statement?) [LaeMi: this is not the gramatical point you are looking for!]
