I hated Denise at times
She was probably the dumbest Cosby kid ever. Even Theo (who was dyslexic) was smarter than her.
But surely, you did know that dyslexia doesn't make you stupid?
Seriously though, I have to agree with you about Denise. She would make several stupid decisions over the years. And it was only huge luck, that she would last for a year living in Africa and end up with Martin.
