Its not so much the pinky,but what fingers the pinky works with.Try using your middle,ring and pinky to do stuff...you'll know what I mean.My Index,middle and pinky all get along fine.My index,middle and ring get along fine,But when the ring and pinky go to work they attempt at hugging each other.Heres a little idea...take some small wrenches and place them between your fingers so there separated a good strech from one another and bind it all up with tape so it stays in place with no effort...now sleep with it like that every night.That will teach them fingers to stay the hell away from each other...if they dont atriphede in the process...

Later! \m/
