Long story short, you’re not “young, inexperienced and innocent” because your thoughts aren’t complicated enough. It’s about being lively and reactive for things, and adulting isn’t about maturing mentally, it’s about doing mundane admin stuff yourself now. So there’s no need to rush into “maturing” and “adulting”. Being young is good. I’d like to be young and stupid and inexperienced with you. But if you’d like to hear my thinking process (and drift off to sleep to it) you’re most definitely welcomed.
