True friends are not chosen, they are just made. They just happen, like part of a natural process we are least prepared to predict and always ready to ignore. Because even though there is a human tendency to get attracted to the people we most want to resemble, this attraction perishes if it is not regularly fed with care and attention from both sides. If you haven't had your lifetime friends yet, then perhaps you need to continue believing and show patience, or perhaps they came but you lacked vigilance.
