Maybe it was because I was at a book sale at Mac today , and it spurred memories of browsing through clearance books at the Carleton bookstore ( their clearance section had quite a few art books and I used to be excited by the books I acquired . Meanwhile , I 'd been looking forward to the book sale but was mostly disappointed by the selection . I did walk away with two art books though -- Face and Installation Art In The New Millenium , which made me happy enough ) .

Question: Why did I end up happy in the end ?
Answer: None of the above choices .I was able to buy a book on art .I was able to buy a book on memories .I was able to buy a book on animals .
