Ugh, that's so rude. I can acknowledge that not everything my mom did to raise me was 100% perfect, but also that she did her absolute best as a fallible human. And that despite the fact that I theoretically had a father for most of my childhood, I maintain she is the ONLY parent who raised me. Things I never realized as a child was that she was the only one who worked for 90% of their marriage(at a really good job), and still did almost all of the parenting and put herself through grad school just because she wanted to. I was a latchkey kid too, and sometimes wanted to be homeschooled or otherwise have had more from either parent - but as an adult I realized that it wasn't an option and that the life my mom led was the only choice she had, largely because of me and my brother. And she never complained or made it seem like we were ever a burden to her(her husband, on the other hand...) and I can only respect the hell out of her for that. Your brother sounds like he's still very childish.
