A friend sent me a cookbook as a present but when it arrived it was a secondhand library book and a bit grotty! I am fairly sure she didnt mean it to be like this but she has asked me about it and is coming round for dinner and so I dont know what to do. I thought about ditching it and buying a new version so that she wouldnt be embarrassed, or I could just not let her see it and make little reference to it (but that might seem rude!) or do I tell her? Help! What would you do?!
