TB leads a double life.

At home, church, and school, TB goes by his given name.  This TB, although far from mild-mannered, focuses on more cerebral pursuits, and of course, agitating his sister.

At camp and sports commitments, however, TB goes by his initials.  This TB is a lean mean competition machine.

The biggest secret of all is why TB pretends like he doesn’t switch between alter egos as it suits him.
