poor old man?

no, that's neither a lego figure nor an old man without arms.
that person – or let's better call it 'thing' – is a traffic robot. he is placed in front of a construction site (instead of a sign) to make sure car's won't crash it.
all he does is moving his 'arms' in all directions with glowsticks in his non-existent hands.
we saw him today on our way to lunch, next to PLATOON KUNSTHALLE.
at first i wasn't doubting it's a real person and felt pity for him. in my thoughts i could see him saying, if he's asked for his occupation: "i am a warning sign."
but then ohyun and udo opened my shortsighted eyes. thanks to them i can go to sleep without thinking what a human rights abusing country korea is.
