Manipulation and overly trusting nature

[Guest guest]

I understand this one, my son had this friend who kept asking him for toys, video games, etc. My son gave him a few things, when I found out, I nicely asked the boys' mother to return them, and she said no. I didn't like the values of the mother or child, but hated to take away a friend from my son. Then this child stopped talking to my son after stealing some video games (my son had said he wasn't supposed to give them to him anymore), but the other reason was even crueler - the mother's latest boyfriend doesn't want her son playing with 'retards'. I don't get shocked by anything anymore, but it still doesn't stop my disgust and disappointment. It makes me sick to think my child has to deal with people who don't appreciate him, but just use and abuse him. Anyone had problems like thiss and how do you find 'nice' friends for your children?

Thank you.
