Actually, I found it deeply insulting when I walked past a little kid who, pointing at me and tugging his mother's hand, said, "Mummy, mummy, look at that policeman..." ;-)
Why, as a student, should it be insulting to be mistaken for a policeman?
Anyway guys, get over it - we all wear uniforms; every day! Whatever your situation, you wear a uniform. And if you don't understand that, you have a wee bit to learn about human nature!!!
