I know a mom who does this kind of crap to her son, it's like she wants his life to be miserable. She's divorced but her ex-husband lives on the same street...in any case she does her damnedest to make sure he doesn't see the ex-husband. She also won't let her son get a drivers' license or a phone. She never supports this kid even though that'd do him a lot of good just now, but she acts like a human pooper scooper for her daughter - she never punishes that girl at all. And what a pity, because this girl really deserves a hefty ass-whooping or two.
Makes me grateful that my mom got divorced from her first husband before having me or my brother. Good call on her part, from what I've heard about this guy; Occasionally abusive Catholic alcoholic...that would've been real fun.
