Do you know rum and raisin in Havendale?

There was a man who told his adopted son that the only way they would know if they are related is if he showed at the market when he needed it but it was one hour late when he tested.  The truth is the adoptive father never did follow this except but once and  it was when he needed help at the airport as he did say she would show up if he needed her help but she also knew the return date and time and she did show up.  He could have taken a taxi.   But, his adoptive son turn these notions into a culture and magnified them as it killed, whole and entire families.
