Ignore the bully? I guess you might tell that to a daughter...
It doesn't work for girls either. You stand up to them and get the crowd on your side.
My dad taught it to me this way.
If you want it to stop... fight the bully.... every single time he bullies you.
If the school calls me and tells me that you have been in a fight, I'm going to give you 10 licks with my belt. If the school kids tell me you lost the fight, I'm going to give you 20. So you decide how hard you want to fight.
I only got bullied once. Got 3 licks from the Principal and 10 from my dad. Never got bullied again by anyone.
