My cousin works at a hotel in Atlanta that hosts a lot of musicians. The whole story about a certain famous rapper demanding all white furniture and throwing a fit if it wasn't perfect is completely made up. He just asked for extra towels like a normal person. I actually believe the magazines know the truth but the boring version doesn't sell copies. They have to build up these crazy legends to make people interested.

Oh man, tell me about it! This whole thing is a master class in suffering.

So when does someone cross the line from learning a skill to acting like an expert? Is it when they fix one leaky faucet and start giving plumbing advice, or is there a real difference between having some knowledge and claiming to be a pro?
