Bought New Vegetarian Cookbook

We made a trip to Border's Bookstore today. When we got back out to the car, Nathan (my 11 year old), asked me what I bought. I told him a vegetarian cookbook. "What?! We aren't vegetarian!" My husband told me that I should probably take it back and get my money back. Do you feel the resistance? It's not like I'm going to force them to be vegetarians. But, it doesn't hurt to eat more veggies and less meat once in awhile.
