Life with ""momma the lendlud"" in an old-style tenement is just about what you think it might be -- an untutored matzos meal memoir filled with affectionate sentiments which pair off about evenly with not only what happened at home but at school or during the summer in the mountains or at first parties. Momma who was youthful in her pedal pushers, active God knows, and attentive, was one of life's handywomen who could cope with anything -- giving an enema to a next door neighbor; putting out a fire; repairing a car; or just sifting through the garbage for some valuable which accidentally disappeared down the dumbwaiter. The scene is Newark, N.J., and the time not too long ago, when life was crowded with neighbors and family and a kind of a busy reciprocity you'll be hard put to find anywhere.
