How It Feels to be Solo Child?

I want to hear from the single childs out there, the single children that grew up who are adults now living a life. I want to hear what was life like growing up? Because I think on a day to day basis, although there's more expenses with each additional kid, logistically it gets complicated when they're older and they have different activities and so forth. But as an only child, who the heck did you play with? What was your your day to day life like and how do you think it's impacted you now? What was it like to grow up as that single child and become an adult? And what do you look back on and think? I wish I had a sibling to pick on, to tease, to borrow from, to play with, to be guided. Really, really curious comment. I'm curious.
