When I was 17
My dad used to work for Florida Power and Light in the 80's. FP&L used to have a week at Disney called "Power Days" where FPL employees got a discount on admission to the Magic Kingdom. When I was 17 I went with my parents to this event. I thought I was too cool for the family scene and wore my Iron Maiden concert t-shirt as a symbol of my rebellion. Disney had a special location for FPL families on the top floor of the Columbia Harbour House and I begrudgingly accompanied my parents to this location for lunch.
I sat alone in a corner in my 'maiden shirt oozing attitude because I was mad I had to be there. As I sat there a CM in a Dale costume walked over to me and gave me the "metal horns" hand sign. I had to laugh. I realized what a jacka** I was being and lightened up immediately. Kudos to whoever did this. This happened over 20 years ago but I still smile when I think of this incident.
Both my boyfriend and I are in our thirties and still rock the 'metal' look. We often wear our band shirts to the parks and I think the CM's like to see someone a little bit different to the usual family member! When we were last there we even got a character to pose for a photo making the 'horns'!!!
