How Do Trains Stay On The Tracks?

An Unnecessary Confrontation

OK so this just happened to me on a quick trip to the corner store. I saw this big ugly bald guy beginning to walk across the street from a set of apartments -- toward the same store I was driving to. He had basically just stepped down onto the road from the ramp that leads up into the parking area for the apartments. I knew I had plenty of time to continue on, without causing him to fear being hit, but I slowed down and made sure he was gonna allow me to do so.

So I park on the side of the store like always. Being the nonconfrontationalist that I am, I waited for him to pass my door before getting out. He proceeds to turn around, and this is the dialogue that ensued:


Him: Good thing I wasn't in your way there dude.. (sarcastically)

Me: Nah..

Him: Oh I wasn't huh? (more sarcasm)

Me: I wasn't gonna hit you.

Him: So much for pedestrians having the right of way.

Me: You mean when you were jay-walking across the street in a dark shirt at night?

Him: Jay walking, my ass..

Me: There's no crosswalk right there - What do you expect me to do, stop right there in the middle of the street?

Him: For a pedestrian, yeah I do!

Me: I was just turning left, and I had plenty of time, Jesus Christ..

Him: Don't bring him into it, he didn't do anything wrong.

Me: Neither did I.


We were already inside the store at this point, and the clerk and another guy were looking at both of us as if there was about to be a gun fight.

I waited in line behind him.. He made his purchase, and turned around and glared at me like a serial killer on his way by.

I was like, "Did that really just happen for no necessary reason whatsoever???"

Imagine you have a little robot that holds a pencil. Set it down on a sheet of paper and give it these instructions:

1.Move forward 3 units and turn right.
2.Move forward 1 unit and turn right.
3.Move forward 2 units and turn left.
4.Move forward 1 unit and turn left.
5.Move forward 2 units and turn right.
6.Repeat.

If the robot makes its turns at 90° angles, it will produce this figure:








But, remarkably, if it turns at 120° it will draw this:








That's pretty crazy!!
