Oh I'm sorry the adults have adult things to talk about, like how that person at work was rude to you, you don't know what this acquaintance meant when they said that unimportant shit they said, and you need to get gas and pick up skim milk tomorrow. So mature!
I'm 40 and married with a kid, and pity the adults who decided to "grow up." I make it a point to NEVER give my work life so much as a passing comment or thought the second I leave it. Life is ridiculous, nonsensical, gallows hilarious, and absurd, better to revel in that than actually be childish and play pretend it's harrumph a super serious undertaking I do declare.
