For Kids (and kids at heart)
Exceptions are like pizza crusts: you never know when one's gonna come out of nowhere and ruin the party.
You can use try-catch blocks like a safety net, but be careful not to get caught in the web of your own making.
Sometimes, you gotta rethrow like a ninja, but don't rethrow too many times or you'll end up with a big mess.
