I used to hate giving up books but I've done it more and more over the last couple of years. For novels - need to get past the first couple of chapters. Just try to get a feel for the book and its characters before I decide whether to keep going. Some books are slow starters but get really good.

When he talks about parties, is he talking about children's birthday parties, because he's acting like he's 10 years old.

I was really tempted to get that the other day when I spotted it, but opted instead for Elizabeth Kolbert's new book.

I've added it to my to read list though.
