At my gym the gymnasts have to call the coaches by their surname i.e Miss whaterever, Mrs whatever, just 'Miss', or Mr whatever. My surname is fairly long and starts with 'bear', and when I first coached my group they were age 5, and couldn't say it, so we shortened to Miss Bear. Now they are older, some have stuck to Miss Bear, some say the whole lot and some stick to Miss - I answer to all!
