I've figured out time travel. I jump around, within a few minutes plus-or-minus, and it works! Also I figured out how the ambiguities of multiple timelines are resolved, somehow it all makes sense. To trigger a time jump, I have to turn the key to start my truck at the same time as doing something else, I think on my phone.

I explain this to a girl named Amy that (in real life) I haven't seen since high school and didn't really know even then. She's sitting at the end of a table as if in a cafeteria, talking to a few other girls. I prepare to demonstrate, but I think two people can't travel in time, and I say it's be hard to understand because your mind puts it all in sense in one timeline. But I prepare to demonstrate, in a minute when she's done talking to her friends, using some method where she is going to cut a shape out of a piece of paper, and then with time travel we'll change it so she cuts out a different shape. Then in her timeline the shape will seem to change. I have it all planned out. The only problem I haven't resolved is how to be in my truck starting the engine while pulling this off.
