Felix and Milo are getting along great but sometimes, like all siblings, they argue. Typically, Felix keeps his cool. Overheard recently:

Milo: - You're not my friend anymore! You'll never ever be my friend ever again.
Felix: - I am still in your family, though. And you know what, Milo, some day, we'll be friend again."

10 minutes later, as they are back to playing happily, Felix drives his point home: "You see, Milo, I told you so. We're friends again."
