MadManInABox11: Woooooot
MadManInABox11: I just discovered this weird human thing…. It's called AIM. Helllllllooooo-oooooh?
MadManInABox11: *sighs* Anyone?
TheGirlWhoWaited has entered the chatroom.
TheGirlWhoWaited: "MadManInABox11?" hmm… Are you who I think you are?
MadManInABox11: That depends… Are you who I think YOU are?
TheGirlWhoWaited: Okay, on the count of three, look up from your computer screen. If we see each other across the room, we'll know.
MadManInABox11: One…
TheGirlWhoWated: Two…
MadManInABox11: LOOK!
TheGirlWhoWaited: It is you! But what's up with the eleven?
MadManInABox11: …My favorite number?
TheLoneCenturian has entered the chatroom.
TheLoneCenturian: Umm… Are you people who I think you are?
MadManInABox11: YES!
TheLoneCenturian: Cool… MadManInABox- I didn't know you did AIM.
MadManInABox11: I didn't know you did either.
TheLoneCenturian: Why are y'all chattin' across the room?
TheGirlWhoWaited: IDK…

#1Granddad: Are you who I think you are?
MadManInABox11: I don't know.
#1Granddad: Well, my first name is Wilfred, if that rings any bells. And I just got my daughter to let me create an AIM account.
MadManInABox11: I know you!
#1Granddad: Well now that we've got that sorted, are YOU who I think you are?
MadManInABox11: Do you know other mad men in old-fashioned blue boxes?
#1Granddad: Point taken.
MadManInABox11: So what's been going on with you lately? …Wait, timelines, gotta get this straightened out. When was the last time you saw me?
#1Granddad: Donna's wedding.
MadManInABox11: That was a year ago for me.
#1Granddad: So… Um… You died and all?
MadManInABox11: Yup! I'm a new man now!
#1Granddad: Um… What are you like?
MadManInABox11: Short. Well, not really short, but just short compared to how tall I used to be. Darker hair (still not ginger ), it's all floppy and annoying, green eyes, and slightly insane!
#1Granddad: Okay than. Gotta go! Donna's calling me, and she sounds annoyed!
MadManInABox11: Give her a hug from me, okay?
#1Granddad has exited the chatroom.
MadManInABox11: Oh, bugger.
MadManInABox11 has left the chatroom.
