I have actually successfully completed therapy. Are you familiar with gangs? Have you ever seen crime families where the sons and fathers all look nearly identical? The feds have dealt with plenty of blood gangs in organized crime families. It is typically very difficult to catch their members because they will often arrest one member who fits the exact description and picture of their target, only to have them fingerprinted and realize that the prints do not match.
If you don’t believe there are crime families that have nearly identical members, consider younger photos of Greg Scarpa, compared to pictures of his son, Greg Scarpa Jr., photographed at around the same age.
