Look at these adults! They're being so adult-y!
Okay, I don't know anything about them so I'm only guessing.
But here are some signs you're finally an adult:
Knowing what terms certain basic financial terms mean
Owning a vacuum cleaner
You recycle
You have a view on politics.
Owning a lawn mower
No longer going home for a Sunday meal
Hosting dinner parties
You greet people with a handshake
