It reinforces my view that you should have to sit a parenting exam, or be tested in some other way. Way too many people become parents who are completely unsuited to it. Sometimes you look at them and you have to wonder what chance their children have, with scum-of-the-earth parents like that.
Last week I saw a little boy finish his drink and his dad took the plastic cup off him and just threw it on the street (when, of course, there were bins less than 10 yards away). That kid will grow up thinking, dad does that so it's okay. A small example, but I believe that's how kids grow up with no social niceties and that "couldn't give a t*ss" attitude.
