>But they passed him

Because schools don't fail kids or hold them back as a matter of policy, and honestly, that doesn't matter. That's not excuse for the mother not knowing what's going on.

>hey passed him without even notifying her that he was absent so often

Maybe they did, maybe they didn't, but she should take an interest. She's raising him. And it isn't like he failed one test. It's years of failed classes and truancy. Are you telling me a parent wouldn't see the signs that would make them at least go and talk to his teachers to see what's going on?
