If I get heads, let's say this is heads, I take a step backwards, or let's say a step to the left. And if I get a tails, I take a step to the right. So in general, I always have a 50, this is a completely fair coin. I have a 50% chance of taking a step to the left. And I have a 50% chance of taking a step to the right. So your intuition there is, if I told you I took 1,000 flips of the coin, you're going to keep going left and right. If by chance you get a bunch of heads, you might end up really kind of moving over to the left.
