Where's the Point?

I think this will be the final installment in our transportation related post series.

You can indicate to drivers where you want to go just by pointing a certain way in Aden. Pointing to the ground means you want to go within that district. Pointing down the road means you want to go to the next district or further. Pointing across the street means you want to go to an adjacent district, but not the one down the road. The bus going your way will pull to the side depending on where you point.

The Catch: It all varies depending on where you are in the city. In Mansoora, across the road means Crater and down the road means Ma'alla. In Crater, down the road (depending on the direction) can mean Ma'alla or Khor Maksar, and across the road means Kalouah. The list goes on.

Now that I know the point, I need to learn where to point.
