That aunt of mine; boy, she used to wear make-up all week long so terrible thick that - well, she started about Wednesday layering it on, and she never washed, and every day she slapped down a new layer. Until Sunday. Then on Sunday she kind of peeled it off to go to church. *** Boy, she was a case; I used to hope she'd skip a Sunday - sleep through to Monday or something - because I knew two weeks' worth of make-up and she'd set up like a statue.
The narrator reflects on his aunt's extravagant use of make-up, which she applied heavily throughout the week without ever washing it off. By Sunday, she would finally remove some of this make-up to attend church, creating a striking appearance. This routine became a sort of ritual for her as she would layer on new make-up each day, accumulating an impressive facade by the weekend.
