A trapeze artist probably starts out when he or she is a kid.
It begins as just wanting to be good at swinging from monkey bars.
Then he acheives that goal, then gets so good that the other kids get jealous
and call him names like, "Monkey Boy" or "Monkey Girl".
So he gets angry by this and thinks,
"I'm going to join the circus someday, and swing professionally!".
Then he actually does join the circus.
One night the people who mocked him are in the audience
and he sees them and yells,
"Look what Monkey Boy has done!", just before he swings from the trapeze.
Then the people who mocked him growing up are probably like,
"I can't believe Monkey Boy still swings from things."

Or maybe it's not like that at all.
