I feel so for Zev and Justin. Justin is so amazing to be so patient with Zev. My son has Aspergers and once they get frustrated, it is usually all over. They have no sense of others at all period. They only rely on themselves and their internal clock and needs. They tend to bond with one person, and if you are lucky like me and Justin you can get in, but it is a lot of patience and work required to keep the person focused. They are extremely intelligent and normall puzzles like that are easy for them, but again time restraints and others are of no impact to them. I bet you Zev did not even realize that others were there, how far they were, etc. I applaud Justin a million times for how amazing he is, and hope and pray my son finds someone else besides his family like that to help him out through life. They are amazing people, but you have to know how to be with them for the relationship to work.
