A Friend Indeed
According to a report in The Journal of Social and Personal Relationships, an acquaintance has a chance of being your friend after about 50 hours of shared activity or discussions. A friend can be a close (or best) friend after about 200 hours.
Our old and former friends know intimate details of a part of our lives, but do not have an idea about our present selves, due to the years or decades of separation. This can feel disorienting, as suddenly a person with whom one was once so close, appears like a stranger.
Know your boundaries, let other people also know them.
