i have been to church often enough with annie and betsey back in boston , and with jean-paul de valdon in paris , to know the basic moves-kneel now , stand now , up-and-down , up-and-down , sing now , pray now-and with my mantilla draped in front of my face , my mumbling lips are obscured from inquiring eyes , like those of carmelita , for she is certainly intent on watching me .
