That mother had no shame!!!
I could totally appreciate it for its emotional power and Monique's performance, but man, when I saw this scene for the 2nd time around... she was one ditzy broad! She gets on a roll, saying "You was born in Decembertime, around when Miss So-and-So died! You remember that, Precious?" Then Precious, with perfect deadpan delivery, says "I was born in November." Then this wacky, wacky person gives this a thought and then says "That's right, you're my Scorpio child! You have to watch out for Scorpios, they can be trouble!"
Basically the whole scene plays out this way. That mom did not have one clue and no shame. I kept waiting her to top her shamelessness and then when Mariah Carey asks "and whose fault was that?" and without missing a beat, crazy mother said "It's this bitch's fault!" She would have thrown her blind grandmother under a bus for an extra helping of Cheetos. Mommie Dearest had nothing on Monique.
