When my friend and I were leaving the building where an exhibition was holding, we saw two little girls on top of this uncompleted building (Mama Put joint) and started yelling for them to get off else they fall. We were wondering who left them unattended to go upstairs. But they knew what they were doing, as they got a mat and dragged it to the position that you can see. My camera couldn’t zoom more for a clearer picture, but I am sure you can make out what is there.
