'Cos the woman was on his side.
According to Ma'ariv, the Admor Mevishna Street in Bnei Brak will now be segregated-- men on one side, women on the other.
I remember when they first suggested seperate buses, the joke was, what's next, segregated streets? So, what's next, seperate cities (perhaps husbands and wives can meet on neutral ground at appointed visiting hours)?
UPDATE: Apparently the men are supposed to walk on the west side of the street, women on the east. The majority of the shops are on the east.
