No, it never happened. I was always taller and fatter than my classmates. Fortunately no one bullied me. I just remember my dad telling me this is what I have to do. My mom confirmed that my dad fought a lot when he was in school and military (mandatory service in his home country).

The parent poster had good results fighting back, but what if it's a bigger or older kid. Tough to fight back. So my dads instructions was to fight inside the school, not at the bike racks.
