The Andersons are a lost cause. Even if they're not taking your note literally, they have become suspicious of your presence, and will be a lot more vigilant. Surviving there will be difficult, doubly so since it's only your first day!
So, you will transfer to the house of Maggie here. This first inspection seems to have proven it houses no pets - a dog or cat would have made its presence known already - and it is not impossible that an Anderson could visit here, should you want to go back to your shrinking machine at some point.
For now, you merely plod your 1/8" tall self toward Maggie's feet, as she holds court before her guests. At only twelve, she's smaller than either Rachel or Taylor, but those bare toes are still gigantic, still imposing.
Maggie claps her hands, a gesture to gain attention, and it certainly works on you. The force required for that simple move is incredible, and the sound thunders across the room.
"Okay!" she says, addressing her cousins. "Let's waste no more time, and decide what we're going to do!"
Oh. She's one of those people. Loves to have everything organised. That should mean there won't be much mess around this room, a blessing and a curse for your tiny survival enterprise.
"So what does everyone wanna do? Ethan?"
"You got a console, yeah? We can get a few rounds in."
"Ugh, let's just watch something on stream and chill," Abby says.
"Still too much effort," Taylor offers. "How about we just listen to some music and chat?"
Maggie considers these options as you close upon her. All sound pretty sedate, which suits you just fine. Reaching the pinky toe, you hope and pray that the conversation is distracting enough for Maggie not to feel your touch.
"Okay, okay," she says, "and I say we should play a fun board game or something! Let's vote on what to do!"
She does stop short of getting pens and paper for everyone to write down their preference, giving you ample opportunity to scuttle atop her foot, your third giant carrier in as many hours. Hopefully you can avoid messing up this time, ride out this visit and get working on your new camp.
