What an incredible story and I find it uplifting in many ways.
Mr Jan Grzebski obviously met a great lady when he met Gertruda. She has obviously devoted the last 19 years of her life to taking care of her husband and believing that the man she married and the father of their children would return to her. That is real, unconditional love.
What a lady.
Also, it shows the incredible resilience of the human body and mind to repair itself. After all these years, Jan now has the opportunity to experience some more of life thanks to the devotion and care of his family and his determination not to give up.
It is better to travel hopefully.............but, always be prepared for the worst!
