Reliable way of fetching a tables full path.. help??

To begin, I am creating a really ugly table that looks like this:

local things = {["1"] = {['1.1'] = {},['1.2'] = {['1.2.1'] = {}}}}

Basically if there was infinite values going up to 1.1.1.1.1.1.1.1.1................ etc...

I would have to use recursion... I don't exactly see how to do it.. On top of that getting its full path like this:

1-->1.2-->1.2.1

seems really impossible. Is there a reliable and efficient method of doing this without memory loss?

What I tried:

new.ImageLabel.MouseButton1Click:Connect(function()
			if t == false then t = true
				new.ImageLabel.Rotation = 0
				local children = things[v]
				if #children > 0 then
					
				end
			end
		end)

I assumed something like this would work but I'd constantly be adding MouseButton1Click up to 100000
