I have a girlfriend (yes, she is an evil "worldy" girl)
Good for you! Evil/ Worldly are the best kind!
You might want to remind your mum that she may one day have grandchildren through you and if she wanted to have anything to do with them she'd better be sensible.
I will never understand the doublestandards either. A friend of mine, who has stopped going to meetings but still believes made a pertinent observation. He said his brothers would have more time for a heroin addict who stole from them, but was studying, than they would for him.
I heard of a young girl (late teens) getting pregnant - her elder father kicked her out. She had to go to a shelter for women. Sane people cannot understand the thought process that makes a father kick out his pregnant teenage girl. Another girl (late teens) got pregnant, claimed she was raped (but did not go to the police), had the child no problems then the "rapist" boyfriend came onto the scene and everything was ignored! Disgraceful.
