Instead, family structures have become fragmented into many different types and individuals now have much more choice in their lifestyles, personal relationships and family arrangements
For example, divorced people can come out angry and bitter, but Stacey argues this is pointing to the difficulties of negotiating new family arrangements
According to the thesis, in the past people's lives were defined by fixed roles and norms, but now individuals have fewer such certainties or fixed roles to follow
