Leaving the place you have lived your whole life, the place where your family and personal life is and going to another country for work for 5 to 10 years will destroy the past life they had.

After 5 10 years that person will almost become part Saudi due to living in another country. And after he comes back no one will be that close, even close family members will feel something different due to the person being away/(out of physical touch) for 10 years
