if you choose to stay home for entertainment, that has a huge effect on your social situation. if you have friends who like to go out for fun you may not spend near as much time with them as you might otherwise be. and what about people who just don't like the same music as you? or don't dress the same as you? is it possible we are more judgemental than we thought? we may take great leaps to befriend those who are obviously of a different way of life but are we inadvertantly opting the less adversely different completely out of our lives? interesting how we tend to choose our company based on our aesthetic preferences.
