Or do they? When my wife and I were shop hopping the last couple of days she asked my opinion about several of the fabrics she was contemplating, and I told her honestly what I thought about them. Some we're just ugly for specific reasons, and others would be difficult to work with, etc. Of course, all just my opinion. She went ahead and bought some, put back others.
So, when you're shopping with friends, do you give an honest opinion when they ask you what you think about it? Or do you just say "Oh, that's lovely." and move on with pawing through the bolts?
