How to script a player to walk towards another player?

I'm trying to make a script so that a player begins walking at a normal speed, as if walking themselves, perfectly towards another player, but then stopping when the other player stops and they're a little bit behind so theres some distance between the two players. I tried using MoveTo through the humanoid, but I don't know how to properly use it so it moves constantly to a player, stops when the player stops, and then keep going when they begin to walk again.
