How can you tell if a player is NOT touching a part in a script?

I know how to tell if they are , but I can't seem to figure out how to tell when they stop touching it or when they aren't

-- Edit

Wait nvm that wont help one moment

Nothing happens when they don't touch it however if you want to do something when they stop touching it, there is an event called TouchEnded

local Part = script.Parent

Part.TouchEnded:Connect(function(PartThatStoppedTouchingIt)
	--Do stuff here.
end)
