When trading pins with cast members do they just have to trade with you no matter if they want what you are trading? Yesterday it was my first ever trade and I traded a 2000 anniversary pin for madame mim. I just kinda said " I want that one" and my wife asked after what if she didn't want mine? I never thought of it. What is the etiquette? Also does anyone have a good way to keep the pins on lanyards? My daughter almost lost 2 pins using those cheap rubber mickey ears.. why did they ever switch from the metal backs?
