Pssssst…
Here’s a secret (no one is supposed to know)…
The entire Joyful Banker experience is for kids. It’s designed to tempt the neglected and ignored kid in you to come out and play. Hey, being a grown-up (a groan-up) isn’t all that great. It adds up to too much time spent being serious, being obligated to one chore after another. Phoey!!! Where does that get you?

Curiosity is at the top of a kid’s job description. It hasn’t got a thing to do with age, either. If you’re smart (or maybe not too smart) you hang onto that your whole life. Because, once it’s gone you’re really old, as in geezer.

And since you know the secret, I guess there’s no harm
in letting you into our clubhouse. Take a look! We’re the
Kid’s Branch at The Banker. So it makes sense for it
to be a TREE HOUSE. Neat, huh?

Don’t say kids are irresponsible! We’re responsible, too!
Just for different things—like fun and curiosity and play.
Sounds like The Banker’s place to me—now doesn’t it?
