Why did I ever have to become an adult with bills and a career and rent and a credit score and stuff? 0/10 do not recommend; just be a child and play kickball eat lollipops.
One of these days, just yell out, "You know what, I'm done. I'm done being an adult, and I'm done with responsibilities! So if any of you need me, I'll be in my pillow fort... coloring."
It might not actually work, but it'll be fun to say.
