Why does nobody warn you about how expensive adulting actually is?

Turns out "adulting" isn't just paying rent and pretending to know how taxes work. It's also $120 for a decent haircut, $50 for a "healthy" salad that wilts by Wednesday, and $300 to replace a tire because you didn't know tires expire. Nobody mentioned how fast your bank account becomes a ghost town once you're not living off ramen anymore.

I hit 30 this year and suddenly my "fun money" is just me crying in the Target clearance aisle. What do you think? Did society lie to us or am I just bad at math?
