Crossing

In Brazil the stop sign on pedestrian crossings is a red hand not a red man. Crossing the road is an adventure in it's self as the road to the beach is six lanes wide! When it is safe to cross it changes to a little green man. I thought it should change to a green thumbs up as that's what everyone does here and says 'Tudo bem!', which I think literally means 'all well', but is kind of used a catch all greeting.
