When you are in cosplay, especially as a kids’ character, you must be mindful of how you act. Two big buttons are on the front of the coat. George R.R. Martin: father of ‘Game of Thrones’ Arnold Schwarzenegger and Linda Hamilton are back! Cursing when they would not do so is not okay, especially if there are young children around. Do not say or do anything that your character won’t do while you are in costume.
