You think to yourself "He seems pretty normal and I'm up for a little car ride to find a dog"
"Yeah sure why not, but only if we drive down this road towards my apartment so I can get home in the meantime." you say you him.
"Sounds like a plan!" he says smiling as you walk around the car to get into the passenger's seat. You guys start driving but when you start to drive he speeds up.
"Shouldn't you be driving a little slower if we're going to find your dog?" you say half laughing. You look over and his face is stone cold and you get an awful feeling in your gut.
The feeling is so bad you plan in your head that at the next stop you're going to jump out of the car. You pull up to the stop sign and he doesn't stop.
New plan, wait it out it's probably all in your head it will be over soon or should you jump out of the moving car.
