Why do the people that do not want to marry or be in a relationship always bring it up ?

Always see people saying "I don't want a wife, girlfriend, kids, house etc" but the only reason they post about it is to get reassurance from others that its ok and to get some validation from people.<br><br>Why do they need to post about something they're happy with and have accepted already? It makes no sense to me and its not something you ever hear from people in relationships or with kids or something.
