Does that mean we can only cross at the lights which refer to our particular bent?
Is there a bisexual or trans-sexual crossing. And what of children who have not yet discovered to joys of sex and partnership? Or those that claim the right to cross wherever they wish, or, indeed, whenever or with whomever. And those who are visually impaired. What does the buzzer sound like for each impending couple. And does a person need to wait until another person can accompany them across? Is there a 'singles' lane?
How complex this is for us Aussies who merely have a red and green light and a beep or buzz. I'll never get to the other side.
