But as time goes on, we are moving backwards closer and closer to the starting point. So this is, we are moving backward. One way to think about it, at this time, we're at two and a half meters. If you go forward about half a second, we are then back at our starting point. So we have to go backwards. And if we look at this point right over here, it looks like we were going backwards this entire time while our curve is downward sloping. But at this point right over here, when we are about, it looks like, five meters behind our starting point, we start going forward again.
