My brother is this type of person, he'll buy lunches for strangers, his gf, and family, take trips with his gf, and family and treat and pay everything first class always putting them first and foremost!.
When his brother or sister come over they will be last people he will talk to, completely ignoring them, and not buying them food or asking if they want anything!. They will be the last for even going on a trip with him!. He refuses to even help check the oil in his mother's car not caring if something happens to her car, and gets angry, but with his gf or others he'll do it happily even a total stranger!?
How could someone hate their own family and show it so!?
We try to be nice to him but this kind of treatment from his is so sad> HelpWww@QuestionHome@Com
