Did anyone else spend most of their time with friends' families as a kid?

Hey everyone. I just stumbled on this post from r/DnD that reminded me a lot of my childhood. The story mentions a teenager who is a "bonus kid," as in they spend a significant amount of time with their friend's family due to issues at home. I'd never heard this term before (and I think it also refers to step-children), but I definitely had that kind of experience growing up. I had two best friends for most of elementary and middle school and spent a ton of my time with them, sleeping over regularly and going out with their families. More often than not, I was happy to let people assume I was actually their kid. It was kind of nice pretending to be "normal" for a while and ignore issues at home. Did anyone else with CEN/emotional neglect have this sort of childhood? Any other "bonus kids" here?
