The little numb feeling in your stomach

Bones

My dad, Tom, and I were in a rugged jeep with his childhood friend, Chad. We were going slightly in the middle of nowhere desert, just short of town.
"These bones.... They form a new kind of dinosaur. I found them already put together so you and these other girls will just have to watch it until I can get back." My dad said as we pulled up to the site. There was a weird, how do I explain it, transportation thing parked a good distant from the camp site. It had long wheels and a huge windshield, probably a whopping 15 feet tall.
"I've been here before," Chad said but no one payed attention to him, he's been all over the world.
We walked up to this camp site in the sand and rubble. Those two girls I was supposed to be watching the bones with were sickly skinny... And tiny.. With sick pale faces. One (assuming the older one) had dark blonde hair, the younger (the super skin and bones girl) and brown and she wore a sad face like she's been through some shit.
"Samuel! Good to see you!" Said my pop, 'man hugging' this dark-haired, scruffy, bearded guy,"how have you been, what is it like to be this close to the bones-"
I walked away looking around at the vehicle, it was so strange. Peered from behind it were the dinosaur bones.
"Hey! Milan! I'll be leaving in a few so come back so I can explain what you'll be doing!"
"Alright dad!" I shout half jogging back to the site.
He got on his knees and put his hands on my shoulders and talked loud enough for only Chad and I to hear,"hey, I have to leave now but I want you to stay here and watch these bones with the other girls,"
"They're creepy looking pop..." I said.
"A little bit," he chuckled,"but here. I'm giving these two things  to you, we'll both have them. One shows video feed but with no sounds, for safety reasons."
"How long will you be gone?" I asked
"Not too long, just keep the camera on the campsite so I can watch what's happening while I'm away. Do this for me, please?"
"I'm not a baby anymore....." I groaned.
"It's for procedure, think of it like that,"
"Ok.... Bye dad," I smiled and he kissed me on the forehead.
