She’d have to make deals with the rats: leave some food out for them so the wouldn’t bite the doors or the babies. The roaches（蟑螂）？Oh ,they were just like part of the family! I wonder how she felt telling those white kids she took care of to brush their teeth after they ate, to wash their hands after they finish bathroom. She could never tell her own kids because there wasn’t soap or water back home. I wonder how my Momma felt when we came home from school with a list of vitamins and pills the school nurse said we had to have .Momma would cry all night , and then go out and spend most of the rent money for pills. A week later ,the white man would come for his eighteen dollars’ rent and Momma would beg him to wait until tomorrow . She had to lie to him that she had lost her wallet or the relief check was coming soon or the white people had some money for her. Tomorrow I’d be hiding in the closet because there was only supposed to be two kids in the flat ,and I could hear the rent man shout at my Momma and call her a cheat. And when he finally went away, Momma put the sacks on her shoes and went off to the rich white man’s house to dress the rich white kids so their mother could take them to a special baby doctor.1.Mother got up at 6 a.m. every day ,because    .
