Grown-ups go to work when they don't feel good.
Grown-ups go to work when they're exhausted.
Grown-ups do things even when they don't feel like it.
Grown-ups have conversations and interactions with people even when they don't like them at all.
Grown-ups eat foods that are good for them even when they taste like hell.
Grown-ups don't pout and complain when they don't get their way.
Grown-ups probably even listen to their voicemail once in awhile.
I'd rather stay here in my room
Nothin' out there but sad and gloom
I don't wanna live in a big old tomb
On Grand Street...
- Tom Waits
