Day one- settling in

I rang the bell. A moment later the white door before me swung open.Before me stood one big monkey boy. Easily 6 foot 6, tipping the scales at 300 and plenty, i'm sure, with a grey furcap still full growing on top of his head. From within i could here the blaring of multiple televisions.
"You must be Mr. Frazzi," he said. "I'm Jim."
"Yes," I replied. "Im here about the third floor"
"Sure, come on in."
Jim opened the door wider and beckoned me to enter. I stepped inside, thru the small foyer and into the living room. I noted it was jammed. A couch, 2 large chairs, desk with 2 office chairs, some side end tables. entertainment center, 2 tvs (a small one sat on an end table) bookcase, and more. I was reminded of the nest homes of the Millisacs of Bransta. Cluttered, yet somehow in place. Disorganized, but appropriate somehow.
A she-ape stood in the entry way between this room and another I could could not quite see into.
This is my wife, Gail," introduced Jim.
"Hi," greeted the she ape, baring her fangs in greeting. Of all the worlds I've been on, only on Earth do the inhabitants bare fangs to show happiness, joy, welcome. It's a little unnerving and takes a bit of getting used to.
The she ape was less then half the size of her male counterpart with hair best described as reddish black. Like females of many species she was brightly garbed in a red top and pinkish pants. Mating rituals on this planet are bit undefined and vary wildly. Was she looking to attract a second, mate i wondered, or was this a norm?
"Hello," I returned.
"Who are you" chirped a little voice. On one of the chairs, before the television on the end table, bounced an ape whelp. He was a bit pudgy, with black fur on his head and noticibly browner skin than his more lightly complected parents.
Jim said, "This is Edwin. He's adopted from Guatemala." He turned to the young ape. "Edwin, this is Mr. Frazzi. He wants to see the third floor"
"Are you going to live here?" queried Edwin, his fangs bared in a hideously big grin.
"Maybe," I smiled back, hoping I wasn't showing an imapprpriate amount of fang.
Next to the door a staircase led upward. Bounding down the staircase came another boy ape, light skinned like his parents, with brownish fur and notibly skinnier than Edwin.
'Hi," I greeted the boy.
"Hiiiiii!" he returned, drawing the word out in an unnatural manner. He waved one of his arms around with almost careless abandon. Intended as a wave, I presumed. Then he dashed back up the staircase.
"That's Xander. Alexander, actually," explained Jim. He's autistic and doesn't quite understand the social niceties."
A typical American family to study and a base to work from. This was looking like a good deal for a Xenosociologist from another world.
A pity they were unaware of the Doom that was destined.....
