Truth. It's a good thing. At least in America, if you say you're telling the truth, you could do all kinds of wacky things. They teach me that all the time where I work: that it's better to tell the truth and say "sorry" and people will forgive you. It's the cover-ups that lead to downfalls.
Anywho, this is a very forgiving bunch. I'm sure if you post some pics of yer cousin, these boys'll forgive and forget before you can say...
Moral lesson: truth. It always comes out, no matter what. Better to fess up because we all do the same things and are pretty forgiving. In fact, I confess that I am really clueless more than half the time!
