The absolute first rule for bodhran players should be this:

Never, ever, under any circumstances, regardless of how friendly they are, regardless of how cute they are, and regardless of how drunk you are you to loan a bodhran to anyone at a session unless you know for a fact that they know how to play the thing!

My wife made the mistake at one of our recent sessions of passing hers to a guy who swore repeatedly that he knew how to play one but just hadn't brought his with him. Yeah, sure. Within 15 seconds I was ready to gore the guy with the pointy end of my banjo. She has made a solemn promise never to do it again.
