Gloria knocks on the door. It opens, after several minutes, and a bleary-eyed woman demands, "What do you want at this hour of the night?"
"Pardon me, ma'am, but have you had any guests this evening? Or otherwise had someone enter or leave the house within the last few hours?"
"What the hell do you want to know that for?"
"Well, it seems that someone who's used the door tonight got some kind of inter-universal bar instead. And a kid from a different universe wandered into this one by mistake."
"...
You're lucky I'm the one who gets Milliways doors or I'd have called the cops or possibly a mental hospital. I'm sorry about the kid, but I get 'em when I get 'em and I can't predict it."
"Will you take my cell phone number and call me the next time you get a door?"
"Alright, since there's a kid involved, but I don't promise my phone'll be in reach next time it happens."
"That's the best I can ask for." She rattles off her number and the door woman writes it down. "Thank you for your cooperation, and I apologize again for having to disturb you at this hour."
"Yeah, yeah. Can't really help it when there's a kid involved. I'll try to keep in touch. G'night."
"Good night!"
And the door closes.
