Talk about growing up - if the FATHER had bothered to take care of his daughter, not just dropping her off unattended to 'keep company' with a man, then there wouldn't be this problem.
You 'fathers' out there are all biting this guys @rse - and he's not in the right, admittedly - but in fact, you're ACTUALLY p1ssed-off because you realise that this could be YOUR daughter, and that you have been neglecting your duties to your child.
So stop bitching at the OP and go and get your own house in order - before YOU become a grandfather to your 14-year-old daughter's bastard child.
