Wow. That was honest. And shitty. I know being bullied--though my HS gang took it to another level. But I wasn't quiet or passive and fists did a lot talking.
Were you a shithead? Well, you didn't help or do better when you knew you should have. BUT, William had the option to stand up and fight for himself. Nothing stops a bully like a broken nose. If he had silenced one of the ring leaders, the rest of you would have changed your tune.
Most kids are dickheads to another at some point, for some duration and HS is a warzone and molding ground for all.
Hell of a confession though, Kiki. Good on you for shedding some of that guilt.
