Cheek-by-jowl

"As we drove at breakneck speed through the streets, I could not help but be overwhelmed by the gaunt and desperate faces of the people, the endless squatter settlements of cheek-by-jowl, single-room shacks surrounded by ankle-deep mud, and the occasional glimpses of the rich apparently oblivious to the suffering around them."

"El-Amarna's crowded houses were separated not by wide streets, but by narrow, winding alleyways through piles of domestic garbage, in urban communities where everyone lived cheek-by-jowl."
