I suppose it was his lack of shame which led to him boasting about his PRIDE AS THE RIGHT HAND MAN OF THE VONGOLA TENTH to anyone with a pair of ears, so that's probably good advise. XD OR IF YOU'RE NOT GOING TO BE ASHAMED ABOUT IT, AT LEAST TRY BEING MORE DISCRETE.

Next time, instead of lying, he should try just politely asking the others to butt out of the fight. IT WOULDN'T ACTUALLY WORK, but well, at least he'd still have his integrity. XD
