I started a book last night that had such a dull first paragraph, that I knew I had to switch before today's post. So I'm trying The Uncoupling by Meg Wolitzer. Here's the first paragraph:

People like to warn you that by the time you reach the middle of your life, passion will begin to feel like a meal eaten long ago, which you remember with great tenderness. The bright points of silver. The butter in its oblong dish. The corpse of a chocolate cake. The leaning back in a chair at the end, slugged on the the head and overcome. Dory Lang had always thought there was a little cruelty in such a warning. It was similar to how, when she had a baby, people always tried to clue her in on what they were sure would befall her. Once, long ago, Dory and her infant daughter were riding a bus in the city, when an old woman leaned over and said, "May I tell you something, dear?" She had a kind face full of valleys and faults. Dory imagined she was about to describe the baby's beauty -- in particular, the curve of the mouth -- and she made her own mouth assume a knowing, pleased modesty. But what the woman said, leaning even closer, was, "You will never have another day in your life that is free of anxiety."

I love this opening, even with its mixed metaphors of passion and baby compliments. I can't wait to keep reading.
What do you think? Would you read on?
