“When you visit a friend’s house, do you find time to browse their bookcases? Does it shock you if they don’t have one?”
Sometimes I do, sometimes I do not, but I do like having a glance over them to see what books they do have. If they don’t happen to have a bookshelf it doesn’t bother me as perhaps they just don’t like to read as much as I do. I do think that they are missing out though by not having booksheves full of interesting books but that is just me!
